## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-06.

- **Endpoint Security**: 81/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - The endpoint enforces authorisation, advertised via RFC 9728 protected-resource metadata.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 520, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
  - The authorisation server supports Client ID Metadata Documents, the current MCP client-registration mechanism.
- **Transport & Reachability**: 0/100
  - Transport blocked by authentication: the endpoint requires auth we don't have to verify streamable-http.
- **Schema Quality & AI Usability**: 0/100
  - Schema blocked by authentication: the endpoint requires auth we don't have to read it.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 0/100
  - Tool coverage blocked by authentication: the endpoint requires auth we don't have to read its tools.
- **Tool Safety**: 0/100
  - Tool safety blocked by authentication: the endpoint requires auth we don't have to read its tools.
- **Capabilities**: 0/100
  - Capabilities blocked by authentication: the endpoint requires auth we don't have to read them.

**Unverified: 6 categories.** Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## Install

### How do I install the HostTracker MCP server?

## MCP tools (65)

### `get_monitor` (~112 tokens)

Read one monitor with its full configuration. Scope 'monitor:read'. Add expand tokens for more detail (settings, uptime, lastResult, lastIncident, subscription, maintenance, attached, spans).

Input parameters:

- `expand` (string|null): Comma-separated expand tokens; defaults to 'settings,uptime'.

Input parameters:

- `id` (string, required): The job id.

### `list_monitor_types` (~40 tokens)

List every monitor type with its label, minimum interval and whether the account's package can create it. Anonymous, but a token adds the per-account limits.

- `id` (string, required): The contact id.

### `describe_api` (~129 tokens)

Describe the HostTracker v2 REST operations available through api_request: their paths, what each one does, its query parameters and its request-body members. Call it with a search term (e.g. 'contact', '/webhook', 'statuspage') before using api_request, so the call is built from the real contract rather than guessed. All timestamps in this API are Unix seconds and all ids are opaque strings.

Input parameters:

- `search` (string|null): Path fragment or operation-id fragment to search for, e.g. '/monitor', 'incident', 'createWebhook'. Omit to list every path.

### `update_maintenance` (~154 tokens)

Reschedule a maintenance window or change what it covers. Scope 'monitor:write'. Only the arguments you pass are changed; a monitorIds list REPLACES the current coverage.

Input parameters:

- `durationSec` (integer|null): New length in seconds.
- `enabled` (boolean|null): Enable or disable the window without deleting it.
- `from` (integer|null): New start instant, Unix seconds.

Input parameters:

- `cursor` (string|null): Opaque cursor from a previous call.
- `limit` (integer|null): Rows per page, 1-50 (default 20).

### `api_request` (~269 tokens)

Call any HostTracker v2 REST operation that no curated tool covers. Look the operation up with describe_api first — the method and path must match a real operation or the call is refused. The caller's token supplies authorisation and its scopes still apply. Writes under /account are refused outright by this server's safety policy. A DELETE, and any bulk write that is not a /validate dry-run, is refused unless confirmed=true - confirm with the user first, then retry with confirmed=true.

Input parameters:

- `bodyJson` (string|null): Request body as a JSON object, for POST/PATCH/PUT.
- `confirmed` (boolean): Required true for a DELETE or a non-validate bulk write, after the user has confirmed.

- `method` (string, required): HTTP method: GET, POST, PATCH, PUT or DELETE.
- `path` (string, required): The v2 path with its ids filled in, e.g. '/monitor/9f2…/incident'. No host, no version prefix.
- `query` (string|null): Query string, e.g. 'limit=10&state=down'. May also be a JSON object of parameters.

### `create_status_page` (~134 tokens)

Create a status page. Scope 'statuspage:write'. The page becomes PUBLIC at its slug — agree the slug, the title and which monitors appear with the user before creating it.

Input parameters:

- `componentsJson` (string|null): JSON array of components, e.g. [{"monitorId":"…","name":"API","group":"Core"}].
- `settingsJson` (string|null): JSON object of page settings, e.g. {"theme":"light","robotsIndex":false}.
- `slug` (string, required): URL slug the page is served at; must be unique.
- `title` (string, required): Page title shown to visitors.

### `update_contact` (~100 tokens)

Partially update a contact. Scope 'contact:write'. Changing the address re-triggers confirmation.

Input parameters:

- `address` (string|null): New address.
- `alertDelay` (integer|null): New alert delay in minutes.
- `groupedAlerts` (boolean|null): Group several alerts into one message.
- `id` (string, required): The contact id.
- `language` (string|null): New message language code.
- `name` (string|null): New display name.

### `bulk_delete_monitors` (~171 tokens)

Delete every monitor a filter selects, as an asynchronous job. HIGHLY DESTRUCTIVE — always show the user the validation count first and get an explicit go-ahead. Called without expectedCount it only validates; the submission needs BOTH confirmed=true and the expectedCount the validation reported, and the API refuses it if the selection drifted meanwhile. Scope 'monitor:write'.

Input parameters:

- `confirmed` (boolean): Must be true, together with expectedCount, to actually delete.
- `expectedCount` (integer|null): The 'matched' number the validation step reported. Required to submit.
- `filterJson` (string, required): JSON selection filter, e.g. {"tags":["staging"]}.
- `idempotencyKey` (string|null): Reuse the same key to make a retry replay instead of deleting twice.

### `bulk_create_monitors` (~175 tokens)

Create many monitors in one asynchronous job. Scope 'monitor:write'. The batch is validated first and, unless submit is true, only the validation report comes back — show it to the user, then call again with submit=true. The submitted job is polled with get_job.

Input parameters:

- `defaultsJson` (string|null): JSON object of defaults applied to every item, e.g. {"interval":5,"tags":["prod"]}.
- `idempotencyKey` (string|null): Reuse the same key to make a retry replay instead of creating twice.
- `itemsJson` (string, required): JSON array of monitor definitions, e.g. [{"type":"http","url":"a.com"},{"type":"ping","url":"b.com"}].
- `submit` (boolean): Set true to actually create them after reviewing the validation report.

### `add_status_page_incident_update` (~135 tokens)

Append an update to a declared incident's timeline (and move its state, e.g. to 'resolved'). Scope 'statuspage:write'. This too is PUBLISHED and notifies subscribers — get the wording approved first.

Input parameters:

- `idempotencyKey` (string|null): Reuse the same key to make a retry replay instead of publishing twice.
- `incidentId` (string, required): The incident id.
- `message` (string, required): The update message shown to visitors.
- `state` (string, required): New lifecycle state: investigating, identified, monitoring or resolved.

### `delete_contact` (~89 tokens)

Delete a contact and every subscription it had. Scope 'contact:write'. DESTRUCTIVE — confirm with the user first (their monitors stop notifying that address), then report the receipt this returns.

Input parameters:

- `confirmed` (boolean): Must be true to actually delete. Call WITHOUT it first: the tool answers with the resource so you can confirm with the user.
- `id` (string, required): The contact id.

### `update_webhook` (~126 tokens)

Change a webhook's url, events, scope, name, or enabled state. Scope 'webhook:write'. Re-enabling an auto-disabled webhook also clears its failure counter.

Input parameters:

- `enabled` (boolean|null): Enable or disable deliveries.
- `events` (string|null): Comma-separated event names that replace the current set.
- `id` (string, required): The webhook id.

- `id` (string, required): The check id (a GUID) from run_instant_check.

### `list_report_types` (~24 tokens)

List the report types, output formats, sections and schedules available. Anonymous.

### `test_webhook` (~78 tokens)

Send a synthetic test delivery and report the endpoint's answer. Scope 'webhook:write'. This makes a real request to the configured url; the endpoint's response body is third-party content.

Input parameters:

- `eventName` (string|null): Event name to simulate, e.g. 'monitor.down'.
- `id` (string, required): The webhook id.

### `generate_report` (~201 tokens)

- `id` (string, required): The group id.

### `create_webhook` (~176 tokens)

Register a webhook. Scope 'webhook:write'. The url must be https and publicly reachable.

- `cursor` (string|null): Opaque cursor from a previous call.
- `limit` (integer|null): Rows per page, 1-50 (default 20).

### `unsubscribe_contact` (~101 tokens)

Remove a contact's subscription to a monitor. Scope 'monitor:write'. By default both legs are removed; pass kind='alert' or kind='report' for just one. Confirm with the user — they stop being notified.

Input parameters:

- `contactId` (string, required): The contact id.
- `kind` (string|null): Which leg to remove: 'alert', 'report' or 'both' (default).
- `monitorId` (string, required): The monitor id.

Confirm a contact with the code it received. Scope 'contact:write'. Ask the user to read the code from their inbox or phone.

Input parameters:

- `code` (string, required): The confirmation code the contact received.
- `id` (string, required): The contact id.

### `subscribe_contact` (~126 tokens)

Subscribe a contact to a monitor. Scope 'monitor:write'. Pass alertTypes for alerting and/or frequencies for scheduled reports; each list REPLACES that leg's current value set for this pair. The contact must be confirmed before anything is actually delivered.

Input parameters:

- `alertTypes` (string|null): Comma-separated alert types: up, down, repeatedlyDown.
- `contactId` (string, required): The contact id.
- `frequencies` (string|null): Comma-separated report frequencies: daily, weekly, monthly, quarterly, yearly.
- `monitorId` (string, required): The monitor id.

### `list_monitors` (~204 tokens)

List the account's monitors, newest page first. Scope 'monitor:read'. Filters combine with AND; omit them all to list the whole account. Returns at most 50 rows plus a cursor for the next page.

Input parameters:

- `cursor` (string|null): Opaque cursor from a previous call's continuation line.
- `id` (string|null): Comma-separated monitor ids.
- `limit` (integer|null): Rows per page, 1-50 (default 20).
- `q` (string|null): Free-text search over name and url.
- `sort` (string|null): Sort column, e.g. 'name', 'state', 'lastChange:desc'.
- `state` (string|null): Comma-separated states to keep: up, down, paused, maintenance.
- `tag` (string|null): Comma-separated tags.
- `type` (string|null): Comma-separated monitor types, e.g. 'http,ping'. See list_monitor_types.

### `bulk_update_monitors` (~167 tokens)

Apply one patch to every monitor a filter selects, as an asynchronous job. Scope 'monitor:write'. Without submit=true only the count and a sample of what would be touched come back — show that to the user first.

Input parameters:

- `filterJson` (string, required): JSON selection filter, e.g. {"tags":["prod"]} or {"monitorIds":["..."]}.
- `idempotencyKey` (string|null): Reuse the same key to make a retry replay instead of applying twice.
- `operation` (string|null): Set to 'resetStats' to clear statistics instead of patching.
- `patchJson` (string|null): JSON patch applied to each selected monitor, e.g. {"interval":5}.
- `submit` (boolean): Set true to actually apply the change.

### `get_account_quota` (~53 tokens)

Read the API quota headroom and the scopes the current token actually carries. Scope 'account:read'. Call this first when another tool returns a 403 — it shows whether the token is simply missing a scope.

### `send_contact_confirmation` (~64 tokens)

Send (or resend) the confirmation code to an unconfirmed contact. Scope 'contact:write'. This delivers a real message to the address; the code itself is never returned to the agent — ask the user for it.

Input parameters:

- `id` (string, required): The contact id.

### `pause_monitor` (~38 tokens)

Pause a monitor: it stops checking and stops alerting until resumed. Scope 'monitor:write'.

Input parameters:

- `id` (string, required): The monitor id.

### `copy_monitor` (~136 tokens)

Copy a monitor to one or more new addresses, keeping its configuration. Scope 'monitor:write'. Copying many addresses answers with a job id — poll it with get_job.

Input parameters:

- `id` (string, required): The monitor id to copy from.
- `includeAlerts` (boolean|null): Copy the alert subscriptions too (default true).
- `includeMaintenance` (boolean|null): Copy the maintenance windows too.
- `includeReports` (boolean|null): Copy the report subscriptions too.
- `name` (string|null): Name for the copies; the address is used when omitted.
- `urls` (string, required): Comma-separated addresses to create copies for.

### `get_status_page` (~37 tokens)

Read one status page with its settings and components. Scope 'statuspage:read'.

Input parameters:

- `id` (string, required): The status page id.

### `get_job` (~92 tokens)

Poll one asynchronous operation: its state, progress and per-item results. A failed job still answers 200 with state='failed'; each failed item carries its own error.

Input parameters:

- `cursor` (string|null): Opaque cursor to continue the item list.
- `id` (string, required): The job id.
- `limit` (integer|null): How many per-item results to include, 1-50 (default 20).

### `run_instant_check` (~291 tokens)

Run a free instant website/host check from HostTracker's global monitoring locations and return per-location results. Requires a token with the 'check' scope (mint at Integrations → API, https://www.host-tracker.com/integrations/api). Starts the check, polls up to ~30s, and returns per-location status plus the public result-page URL; a check that is still running comes back partial with the ids to poll.

Input parameters:

- `device` (string|null): Device-emulation profile for a waterfall/pageSpeed check; one of the device tokens from list_check_types.
- `pools` (string|null): Comma-separated location pools to run from, e.g. 'europe,northamerica'. Unknown pool names are refused by the API, which names the offender.
- `strictTls` (boolean): http checks only: validate the TLS handshake strictly. An untrusted root, an incomplete chain, a hostname mismatch or a self-signed certificate fails the handshake and is recorded on the result's TLS…
- `type` (string|null): Check type; one of the tokens from list_check_types (default http). 'pageSpeed' is accepted as an alias for 'waterfall'.
- `url` (string, required): The site or host to check, e.g. example.com or https://example.com

### `get_account_usage` (~36 tokens)

Read how many monitors, contacts, reports and maintenance windows the account uses out of what its package allows. Scope 'account:read'.

### `delete_webhook` (~89 tokens)

Unregister a webhook and stop its deliveries. Scope 'webhook:write'. DESTRUCTIVE — confirm with the user first; pending deliveries are dropped and the signing secret cannot be recovered.

Input parameters:

- `confirmed` (boolean): Must be true to actually delete. Call WITHOUT it first: the tool answers with the resource so you can confirm with the user.
- `id` (string, required): The webhook id.

### `delete_monitor` (~85 tokens)

Delete one monitor and its subscriptions. Scope 'monitor:write'. DESTRUCTIVE and not undoable — confirm with the user first, then report the deletion receipt this returns.

Input parameters:

- `confirmed` (boolean): Must be true to actually delete. Call WITHOUT it first: the tool answers with the resource so you can confirm with the user.
- `id` (string, required): The monitor id.

### `redeliver_webhook` (~80 tokens)

Resend a previously recorded delivery to the same endpoint. Scope 'webhook:write'. The receiver sees the same delivery id, so a correctly-written consumer deduplicates it.

Input parameters:

- `deliveryId` (string, required): The delivery id (d_… ) from list_webhook_deliveries.
- `id` (string, required): The webhook id.

### `update_monitor` (~162 tokens)

Partially update a monitor. Scope 'monitor:write'. Only the arguments you pass are changed; everything else stays as it is.

Input parameters:

- `addTags` (string|null): Comma-separated tags to add.
- `id` (string, required): The monitor id.
- `interval` (integer|null): New check interval in minutes.
- `name` (string|null): New display name.
- `pools` (string|null): Comma-separated location pools that replace the current pinning.
- `removeTags` (string|null): Comma-separated tags to remove.
- `settingsJson` (string|null): Type-specific settings as a JSON object.
- `tags` (string|null): Comma-separated tags that REPLACE the current set.
- `url` (string|null): New address.

### `create_monitor` (~228 tokens)

Create a monitor. Scope 'monitor:write'. Confirm the target and interval with the user first — a monitor consumes an account slot and starts alerting. Attach contacts afterwards with subscribe_contact.

Input parameters:

- `dryRun` (boolean|null): Set true to validate only, creating nothing.
- `enabled` (boolean|null): Whether the monitor starts enabled (default true).
- `interval` (integer|null): Check interval in minutes; must be one of the account's allowed intervals.
- `name` (string|null): Display name; defaults to the url.
- `pools` (string|null): Comma-separated location pools, e.g. 'allworld' for everywhere. At least one is required when the type needs locations.
- `settingsJson` (string|null): Type-specific settings as a JSON object (see the monitor type's schema).
- `tags` (string|null): Comma-separated tags.
- `type` (string, required): Monitor type, e.g. http, ping, port, waterfall, sslExp, domainExp. See list_monitor_types.
- `url` (string|null): The address to monitor.

### `comment_incident` (~66 tokens)

Annotate an incident with a note (for example the root cause) and get the incident back. Scope 'monitor:write'. The comment replaces any previous one.

Input parameters:

- `comment` (string, required): The note to store on the incident.
- `id` (string, required): The incident id.

### `delete_maintenance` (~86 tokens)

Cancel a maintenance window. Scope 'monitor:write'. DESTRUCTIVE — confirm with the user first; cancelling an ACTIVE window makes its monitors start alerting again immediately.

Input parameters:

- `confirmed` (boolean): Must be true to actually cancel. Call WITHOUT it first: the tool answers with the resource so you can confirm with the user.
- `id` (string, required): The maintenance window id.

### `list_locations` (~143 tokens)

List the location pools checks can run from (and, with agents=true, the individual monitoring locations). Pool ids are what the 'pools' argument of create_monitor and run_instant_check takes; 'allworld' means everywhere.

Input parameters:

- `agents` (boolean): Set true to list individual agents instead of pools.
- `country` (string|null): Comma-separated ISO country codes to filter agents by.
- `cursor` (string|null): Opaque cursor from a previous call.
- `limit` (integer|null): Rows per page, 1-50 (default 50 for pools).
- `pool` (string|null): Comma-separated pool ids to filter agents by.

### `list_status_pages` (~58 tokens)

List the account's status pages. Scope 'statuspage:read'.

Input parameters:

- `cursor` (string|null): Opaque cursor from a previous call.
- `limit` (integer|null): Rows per page, 1-50 (default 20).

## Common questions

### What is the HostTracker MCP server?

HostTracker is an MCP server listed in the public MCP registry as io.github.HostTracker/hosttracker. Website uptime monitoring: run checks from 300+ locations, manage monitors, alerts and incidents. This page covers its hosted endpoint (https://mcp.host-tracker.com/mcp).

### Is the HostTracker MCP server safe to use?

HostTracker scores 32 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the HostTracker MCP server expose?

HostTracker exposes 65 tools: get_monitor, delete_status_page, create_maintenance, create_contact_group, get_uptime_summary, and 60 more. Their descriptions and schemas cost roughly 7,341 tokens of context every time the server is loaded.

### Does the HostTracker MCP server require authentication?

Yes. HostTracker asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

### Is the HostTracker MCP server still maintained?

HostTracker is still listed as active in the MCP registry. We last reached this channel on 6 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
