Tools (51)

As the server listed them on Oct 25, 2026. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • add_to_watchlistAdd Company to Watchlist

    Add a company to the user's watchlist. Identify by KRS (10-digit) or NIP (10-digit). Supports both KRS companies and CEIDG sole proprietorships (via NIP).

  • add_watchlist_batchBatch Add Companies to Watchlist

  • check_signupCheck Compabase Signup Status

    Poll a request_signup session. When the user has confirmed email, returns mcp_key once and cursor_mcp_json to write to MCP config. Call every 3 seconds until status is ready, expired, or already_delivered. No auth required.

  • count_companiesCount Polish Companiesread-only

    Count KRS companies matching given filters. Returns a single number — no company list. Does not count JDG in this tool (full CEIDG is in Compabase; listing is RODO-gated). Sparse or zero counts in JDG-dominated PKDs include a `hint`.

  • create_api_keyCreate REST API Key

    Create a new REST API key (cb_…). The raw key is returned once and cannot be retrieved later.

  • create_mcp_keyCreate MCP Key

    Create a new MCP key (mcpk_…). The raw key is returned once and cannot be retrieved later.

  • delete_api_keyRevoke REST API Keycan change or delete data

    Revoke (deactivate) a REST API key by its ID. The key stops working immediately.

  • delete_byok_keyRemove Bring-Your-Own-Key Providercan change or delete data

    Remove a configured BYOK provider key. After removal, the platform falls back to its own model access.

  • delete_mcp_keyRevoke MCP Keycan change or delete data

    Bulk file export of companies matching filters (CSV / XLSX / JSON). Up to 500 rows per call. Default `fields=contacts_only`: name, NIP, KRS, city, email, phone, website — small enough to use in-chat. `fields=summary` adds location, PKD, latest revenue/profit. `fields=full` is the complete dump (change history, rankings, people, enrichments, CSV twins) and often exceeds MCP client limits. Consumes export quota only after the file is built successfully. For a short list of emails after search_companies, use search with fields=contacts_only instead.

  • get_byok_keysGet Bring-Your-Own-Key Providersread-only
