Available components
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. How we score → Why this is hard to score →
Endpoint Security97
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- The endpoint enforces authorisation, advertised via RFC 9728 protected-resource metadata. View diagnostics → Pass
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
- The authorisation server supports Client ID Metadata Documents, the current MCP client-registration mechanism. View diagnostics → Pass
Transport & Reachability0
- Transport blocked by authentication: the endpoint requires auth we don't have to verify streamable-http. See how to fix → View diagnostics → Unverified
Schema Quality & AI Usability0
- Schema blocked by authentication: the endpoint requires auth we don't have to read it. See how to fix → Unverified
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified

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. Claim this server and supply a read-only token to verify it and lift the score.
How do I install the Croft MCP server?
Croft is a hosted endpoint at https://mcp.oncroft.net/, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

grant_connector Grant connector to app ~131
Gives one of your apps access to a connector. The app can then call the connector's operations. Note: this lets the app's code, and everyone the app is shared with, use the connector's credential. A connector an admin has marked admins-only can only be granted by an admin. Some connectors require admin approval: when a creator grants one of those, the grant is created as 'requested' and an owner/admin must approve it (they're emailed) before the app can use it — owners/admins granting it are approved automatically.

propose_connector Propose connector ~192
Creates a new API connector as a DRAFT from the vendor's API docs: you supply the base URL, auth style, and an operations manifest. A workspace member (owner, admin, or creator) then opens the panel and adds the credential to activate it — the credential never passes through you. auth_style is bearer|header|query|basic; for header/query also give auth_param (the header/param name).

| path | string | – | – |
No examples provided.
request_public_data_access Request public data access ~112
For an app that has PUBLIC routes: request permission for it to use protected resources (its granted connectors AND other apps' shared data). Public apps are blocked from these by default so a public page can't leak workspace data. If you (the caller) are an owner or admin, this is granted immediately; if you're a creator it creates a request that an owner/admin approves (they're emailed). Call this when building a public app that also needs a connector or shared data.
| Name | Type | Req | Description |
|---|---|---|---|
| app | string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| app | string | – | – |
| public_data_access | boolean | – | – |

| app | string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| deploy_job | integer | – | – |
| status | string | – | – |
No examples provided.
set_database_sharing Set database sharing ~215
Turns this app's database sharing on or off. Off by default (the database is private). When on, other apps in the same workspace may read AND write this app's SQLite database through Croft's internal broker at http://croft-data:8080/q/<this-app-name> (send {"sql":"…","params":[…]}), and this app is listed to other apps as reusable shared data. By default apps that have PUBLIC routes cannot read this shared data (a leak guard); an owner/admin can pass allow_public: true to let public apps read it too. Turn sharing on for an app whose data other apps should reuse — e.g. a CRM's contacts list that an invoicing app also needs.
| Name | Type | Req | Description |
|---|---|---|---|
| allow_public | boolean | – | Owner/admin only. true lets apps with public routes read this shared data (default false — public apps are blocked). |
| app | string | yes | – |
| shared | boolean | yes | true to share this app's database with the workspace; false to keep it private. |
| Name | Type | Req | Description |
|---|---|---|---|
| allow_public | boolean | – | – |
| app | string | – | – |
| shared | boolean | – | – |
No examples provided.
set_public_paths Set public paths ~126
Sets which of an app's paths are reachable WITHOUT login. By default an app is fully private (workspace login required everywhere). Pass the complete desired list of specific paths (e.g. ["/survey"]); each listed path and everything under it becomes public, everything else stays private. An empty list makes the app fully private again. The whole app cannot be made public — root or wildcard paths are rejected.
| Name | Type | Req | Description |
|---|---|---|---|
| app | string | yes | – |
| paths | array | yes | Full list of public paths, each starting with / (e.g. "/survey"). Empty to make fully private. |
| Name | Type | Req | Description |
|---|---|---|---|
| app | string | – | – |
| public | boolean | – | – |
| public_paths | array | – | – |
No examples provided.
set_schedules Set scheduled tasks ~135
Sets the app's scheduled tasks. Each is { name, cron, path }: on the cron (standard 5-field, UTC) Croft makes an internal POST to the app's path, and the app does the work (e.g. send a daily email, sync an API). Use this for anything recurring instead of writing your own cron — it survives deploys and reboots and is shown in the panel. Also implement the endpoint (e.g. a POST route at that path). Pass the full desired list; an empty list clears all schedules.
| Name | Type | Req | Description |
|---|---|---|---|
| app | string | yes | – |
| schedules | array | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| app | string | – | – |

set_secret Set secret ~50
Set (or replace) an env secret for an app. Value is stored encrypted and injected at deploy.
| Name | Type | Req | Description |
|---|---|---|---|
| app | string | yes | – |
| key | string | yes | – |
| value | string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| key | string | – | – |
| ok | boolean | – | – |
No examples provided.
status App status ~83
Reports an app's deploy and health status. `live` is true only when the latest deploy has fully succeeded; `deploy_state` gives the current stage (queued, running, succeeded, or failed). Read-only and safe to call repeatedly — each call returns the current stage, so it can be polled to follow a deploy's progress.
| Name | Type | Req | Description |
|---|---|---|---|
| app | string | yes | – |

No examples provided.
write_files Write files ~72
Writes files into an app's git repo and commits them (as 'Claude via Croft'). files is a list of {path, content}. Committed files are staged in the repo; they are not built or published until the app is deployed.

What is the Croft MCP server?
Croft is an MCP server listed in the public MCP registry as net.oncroft/croft. Deploy and host the apps your AI assistant builds, a real server, database, and shareable URL. This page covers its hosted endpoint (https://mcp.oncroft.net).
Is the Croft MCP server safe to use?
Croft scores 39 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 Croft MCP server expose?
Croft exposes 26 tools: get_platform_conventions, list_apps, create_app, get_app, read_file, and 21 more. Their descriptions and schemas cost roughly 1,900 tokens of context every time the server is loaded.
Does the Croft MCP server require authentication?
Yes. Croft 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 Croft MCP server still maintained?
Croft is still listed as active in the MCP registry. We last reached this channel on 2 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
