Peliqan has an out-of-the-box MCP Server. However, you can also build custom MCP Servers in Peliqan. You can use the Peliqan MCP Server template to get started. You can extend this template by adding your own “tools”, these are Python functions decorated with @mcp.tool().

1. Install the “MCP Server” script from the app templates:

2. Add an API endpoint (method POST) and link it to the “MCP Server” script (this is the API handler script). Click here for more info on how to publish an API endpoint in Peliqan.

3. Update the credentials (API key) in your script and store in the Peliqan Secret Store.
