The 54 tools it listed

"Read only" and "Changes data" are the server's own marks. Underlined parameters are required.

  1. add_to_watchlist

    Add 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).

    krs nip

  2. add_watchlist_batch

    Batch Add Companies to Watchlist

    Add multiple companies to watchlist in one call. Provide an array of KRS/NIP identifiers (max 500). Resolves identifiers to companies, skips duplicates, respects plan limits.

    identifiers

  3. check_signup

    Check 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.

    setup_id client

  4. count_companiesRead only

    Count Polish Companies

    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 REST API Key

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

    name

  6. create_mcp_key

    Create MCP Key

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

    name

  7. delete_api_keyChanges data

    Revoke REST API Key

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

    key_id

  8. delete_byok_keyChanges data

    Remove Bring-Your-Own-Key Provider

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

  9. delete_mcp_keyChanges data

    Revoke MCP Key

    Revoke (deactivate) an MCP key by its ID. Cannot revoke the key currently in use. The key stops working immediately.

    key_id

  10. execute_sqlRead only

    Execute Read-Only SQL

    Execute a read-only SQL SELECT query against the Compabase database. Use when dedicated tools are not enough (aggregations, joins, custom analysis). Returns at most row_limit rows per call depending on the plan (Free 100, Pro 500, Scale 1000); if truncated is true, aggregate inside SQL (GROUP BY, COUNT, AVG, percentile_cont) instead of listing raw rows.

    query

  11. export_companies

    Export Companies to CSV

    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.

    name krs nip city county region pkd all_pkd revenue_min revenue_max is_active format locale limit fields

  12. get_byok_keysRead only

    Get Bring-Your-Own-Key Providers

    List configured Bring-Your-Own-Key (BYOK) provider keys status. Shows which providers (openai, claude, gemini) have keys configured, with prefix and last-used date. Never returns the actual key.

    Get company registry profile and headline financials for one latest filed period (`financials.period_to` / `financial_period_to`): revenue, profit, costs, assets, estimated_value (Ohlson/RIM equity estimate), PKD, address, plus contacts when on record, full address, share capital, representation, recent KRS changes and `vat` (MF white list: VAT status, VAT registration date, bank accounts, removal/restoration, date Compabase checked it). All money fields in this response are that same period — there is no nested summary from a different year. NIP lookup also returns a CEIDG/JDG firm when it has a public contact email (RODO). Does NOT include balance-sheet line items (cash, receivables, inventories). For those or earlier years, use get_financials.

    Search Polish Companies

    Search and filter Polish KRS companies (spółki). Compabase also holds the full CEIDG/JDG register; this tool does not browse JDG — those without a public contact email are hidden because of RODO. Default `fields=summary` returns a compact row (name, NIP, KRS, location, PKD, latest financials, email/phone/website) — small enough for MCP clients. `fields=contacts_only` is name/NIP/KRS/city/email/phone/website only. `fields=full` returns every company_search column plus contacts and may exceed client size limits. Use for rankings, sector filters, city/county/region browsing, name search, or NIP/KRS lookup. When a PKD is mostly JDG, a sparse result includes a `hint` (full CEIDG is in the database; listing is RODO-gated). Do not call export_companies just to get a handful of emails or phones.
