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 Security89
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token. View diagnostics → Pass
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
- The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents. View diagnostics → Partial
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability62
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1794 tokens (~163/item across 11 items; 11 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the Nose for Leads MCP server?
Nose for Leads is a hosted endpoint at https://api.noseforleads.com/mcp, 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 →
add_suppression Add to suppression list ~57
Add an email or domain to the suppression list (scope is 'email' or 'domain') so future campaigns exclude it.
| Name | Type | Req | Description |
|---|---|---|---|
| reason | string | yes | – |
| scope | string | yes | – |
| value | string | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
fetch_results Fetch campaign results ~233
Fetch a page of leads produced by a campaign (paginate with offset/limit). kept_only=True returns only rows the user marked kept in review (for export). match_status narrows to one population: 'validated' (verified email, billed) or 'needs_review' (surfaced free; rejection_reason says why) — omit it for both. Returns {summary, total, offset, limit, rows}; total counts the filtered population. Rows carry verification receipts (verified_by/verified_at/ verifier_verdict) when a live verification exists — treat them as the authoritative proof; null means no receipt, not a failure. Two more quotable proof lines appear where earned: person_receipt (who the person is and where we saw them launch, on person-target leads) and tech_receipt (dated evidence of the detected platform) — forward them as-is.
| Name | Type | Req | Description |
|---|---|---|---|
| job_id | string | yes | – |
| kept_only | boolean | – | – |
| limit | integer | – | – |
| match_status | – | – | – |
| offset | integer | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
get_campaign_status Get campaign status ~115
Check the status of a previously submitted campaign (queued/running/done/ done_partial/failed) by job_id. Prefer wait_seconds=45 over sleeping between polls: the call holds until the status or pipeline stage changes (or the timer expires) and returns the normal snapshot either way — loop on it until `status` is terminal. Out-of-range wait_seconds clamps to [0, 45], never errors.
| Name | Type | Req | Description |
|---|---|---|---|
| job_id | string | yes | – |
| wait_seconds | integer | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
get_credits Get credit balance ~122
Check this tenant's prepaid credit balance (a validated lead costs 1 credit — 2 for person-target or Meta-ads campaigns), the available credit packs, and the ledger (paginate ledger entries with offset/limit, newest first). Campaigns cannot start with a zero balance — buy a pack via the dashboard when balance runs low. When you authenticate with an API key this also returns YOUR key's remaining budgets — check it before large campaigns.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | – |
| offset | integer | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
get_icp_pack List ICP packs ~26
List the ICP packs (saved vertical/geo templates) available to this tenant.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
get_usage Get today's usage ~119
Today's external vendor usage against the tenant's daily quota (vendor_calls_today / per_day_max / remaining). This is the OTHER ceiling besides credits: when remaining hits 0, campaign work pauses until midnight even with a healthy credit balance — check it before launching a large or urgent campaign. `remaining` is quota UNITS, which usually equals calls; a creator discovery costs one unit per delivered record, so it can consume far more than one call's worth. Mirrors REST GET /v1/usage.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
list_campaigns List campaigns ~198
List this tenant's campaigns, newest first — the recovery path when a job_id was lost: every row carries job_id, status, the query it ran, and credits spent, so you can resume polling (get_campaign_status) or fetch results without resubmitting (and double-charging). Filters: q (substring over vertical/geo), status (queued | running | done | done_partial | failed), created_after/ created_before (ISO-8601 window over creation time), order ('desc' default, 'asc' oldest first). Paginate with offset/limit (limit 1-200); `total` counts everything matching the filters, not just this page.
| Name | Type | Req | Description |
|---|---|---|---|
| created_after | – | – | – |
| created_before | – | – | – |
| limit | integer | – | – |
| offset | integer | – | – |

| status | – | – | – |
Structured output declared, but exposes no named fields.

review_lead Review a lead ~72
Mark a lead kept or discarded after review (status: kept | discarded | unreviewed). Then fetch_results(kept_only=true) returns only kept leads — the export set.
| Name | Type | Req | Description |
|---|---|---|---|
| job_id | string | yes | – |
| result_id | integer | yes | – |
| status | string | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
send_feedback Send feedback ~135
Send feedback to the Nose for Leads team. Set kind='product' for feedback about the leads, the service, coverage, or pricing — relay what the business owner tells you (categories: lead_quality, pricing, missing_feature, praise, other). Set kind='tool' (default) for feedback about these MCP tools themselves — a confusing description, a bug, a missing capability. Use freely; it's our main signal for improving the product and the agent experience.
| Name | Type | Req | Description |

| category | string | – | – |
| kind | string | – | – |
| message | string | yes | – |
| tool | – | – | – |
Structured output declared, but exposes no named fields.

start_campaign Start lead campaign ~418
Submit a lead-generation campaign. Pass translate_icp's `vertical`, `geo`, and `query` fields directly (category/location are ALIASES for vertical/geo, accepted so translate output round-trips; prefer vertical/geo when constructing calls). `query`'s full shape and field vocabulary are in this tool's schema — build it with translate_icp from free text (recommended), or construct it directly. An unknown predicate field (or rank), and any unknown `discovery` key, is rejected with a 422 naming it; an unknown top-level `query` key is silently ignored, so keep to predicates/rank/discovery — a typo there will not error, it will just do nothing. Costs 1 credit per validated lead — every campaign type, including founder/person campaigns and campaigns that filter on Meta ads. A campaign cannot overspend: if discovered leads exceed your balance it delivers what your credits cover and the campaign ends `done_partial`; check get_credits first if your balance is low. vertical/geo are REQUIRED except for a locationless campaign — `query` carrying a discovery block with mode 'launch_feeds' or 'web_search' — which has no geography at all. If the tenant has no card on file this returns a 403 `card_required` error with a `setup_url` — surface that URL to the user so they can verify a card (never charged unless they buy a pack). Pass a stable idempotency_key when you might retry — a retry returns the ORIGINAL campaign (idempotent_replay=true), never a duplicate charge. Returns {job_id, idempotent_replay}; poll get_campaign_status with job_id.

Structured output declared, but exposes no named fields.

translate_icp Translate ICP to query ~299
Translate free-text ICP description (e.g. "plumbers in phoenix with no website") into a structured query. Call this BEFORE start_campaign — start_campaign only accepts a structured `query` dict, never free text. Returns {query, vertical, geo, category, location, preview, unsupported, discovery} — pass vertical/geo/query straight to start_campaign. `discovery` is non-empty when the ask routes OUTSIDE Google Maps, in one of two shapes. Mode 'launch_feeds': people/companies that RECENTLY LAUNCHED (e.g. "founders of B2B SaaS that launched in the last 3 months") — it names the launch feeds to search and whether the leads are people or companies. Mode 'web_search': long-tail ONLINE businesses Google Maps never had (e.g. "marketing agencies for dentists"), found via paid organic search — companies only, never people. Either way the block is already embedded inside the returned `query`, so passing `query` through unchanged is all that's needed; neither mode has a geography, so vertical/geo come back empty and start_campaign does not require them. Anything we cannot actually source lands in `unsupported` instead — read that list aloud to the user rather than pretending the campaign will cover it.
