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 WatchlistAdd 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 WatchlistAdd 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.
check_signupCheck Compabase Signup StatusPoll 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-onlyCount 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 KeyCreate a new REST API key (cb_…). The raw key is returned once and cannot be retrieved later.
create_mcp_keyCreate MCP KeyCreate 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 dataRevoke (deactivate) a REST API key by its ID. The key stops working immediately.
delete_byok_keyRemove Bring-Your-Own-Key Providercan change or delete dataRemove a configured BYOK provider key. After removal, the platform falls back to its own model access.
delete_mcp_keyRevoke MCP Keycan change or delete dataRevoke (deactivate) an MCP key by its ID. Cannot revoke the key currently in use. The key stops working immediately.
execute_sqlExecute Read-Only SQLread-onlyExecute a read-only SQL SELECT query against the Compabase database. Use when dedicated tools are not enough (aggregations, joins, custom analysis).
export_companiesExport Companies to CSVBulk file export of companies matching filters (CSV / XLSX / JSON). Up to 500 rows per call.

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-onlyList 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.
