MCP connector for Claude

Portuguese Public Contracts

Open public tenders (anúncios de procedimento) from the Diário da República, and awarded public contracts from the Portal BASE (IMPIC): who bought what, from whom, for how much and by which procedure. Tenders need no credentials; contract data needs a Portal BASE API token issued by IMPIC.

Add it to Claude

1. Create an account and add credits at https://openjack.dev; copy your connection key.
2. In Claude, open Settings → Connectors → Add custom connector and paste https://contratos-publicos.openjack.dev/mcp.
3. Click Connect. You will be asked for the connection key and your BASE Contratos Públicos credentials.

How your data is handled

Your BASE Contratos Públicos credentials are validated once, then stored encrypted with a key that only the token issued to your Claude account can unwrap. Disconnecting the connector in Claude revokes that token. The connector keeps no logs and no cache, and stores none of the data it passes to Claude. Every tool is read-only.
