Which MCP servers are Nose for Leads's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry namecom.noseforleads/leads-mcpverified in the MCP registry

The registry name sits under noseforleads.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

  • Checked on 3 of the 7 days it takes to judge reliability.

Once connected

  • For "Turn a plain-language description into a list of matching businesses", the likely first call is translate_icp.
  • For "Run list building from an AI agent and receive a validated list", the likely first call is translate_icp.
  • add_suppression, send_feedback change data without a sign-in: anyone with the address can call them.
  • Parameters are untyped or undescribed in 9 of 11 tools: check arguments before calling.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Worth a look

  • Tools that change data, on a server that answers without a sign-in: add_suppression, send_feedback

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • translate_icp

    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…

  • start_campaign

    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…

  • get_campaign_status

    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)…

  • fetch_results

    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…

  • get_icp_pack

    List the ICP packs (saved vertical/geo templates) available to this tenant.

  • add_suppression

    Add an email or domain to the suppression list (scope is 'email' or 'domain') so future campaigns exclude it.

  • review_lead

    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.

  • get_credits

    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…

  • list_campaigns

    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…

  • get_usage

    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…

  • send_feedback

    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)…

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "leads-mcp": {
      "type": "http",
      "url": "https://api.noseforleads.com/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http noseforleads https://api.noseforleads.com/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://api.noseforleads.com/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
