How to connect Compabase to Perplexity
Compabase gives Perplexity read-only access to data on 3M+ Polish companies from the KRS and CEIDG registers (financial statements, management and owners, public tenders, insolvency and sanctions records).

When the client asks you to sign in, the Compabase page opens: sign in to your Compabase account and click Allow. The client then receives its own access token.

- Name it Compabase and paste https://compabase.com/api/mcp/connect as the MCP server URL.
- Set Authentication to OAuth and Transport to Streamable HTTP.
- Tick the acknowledgement and click Add.
- Click the connector card to sign in to Compabase, click Allow and enable it.

Cost and access
You need a Compabase account; the free plan includes a monthly allowance of MCP queries and paid plans raise it. You sign in once in the OAuth window; no API key to copy. Prefer a static key? Create an MCP key at https://compabase.com/integrations?tab=mcp and send it as Authorization: Bearer mcpk_… to https://compabase.com/api/mcp.
All tools are read-only. See the MCP documentation for every tool, or the GitHub repository.
