How do I install Firsay?

It runs as a remote server. In Claude Code: claude mcp add --transport http firsay 'https://firsay.io/api/mcp' --header 'Authorization: <Bearer fsy_... personal API key from firsay.io (Account, API keys & MCP)>'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does Firsay need an API key?

Yes. It expects Authorization, which you set in its configuration.

Who maintains Firsay?

It is published by io.firsay. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
