MCP Commands¶

Manage Model Context Protocol server connections.

missy mcp list¶

missy mcp list

Shows connected servers with alive status and tool count.

missy mcp add¶

missy mcp add filesystem --command "npx @modelcontextprotocol/server-filesystem /tmp"
missy mcp add postgres --url "http://localhost:3000"

Option	Description
`--command`	Stdio command to launch the server
`--url`	HTTP URL for an already-running server

missy mcp remove¶

missy mcp remove filesystem

missy mcp pin¶

Pin the tool manifest digest for supply chain verification.

missy mcp pin filesystem

Computes a SHA-256 digest of the server's tool manifest and writes it to ~/.missy/mcp.json. On future connections, a digest mismatch refuses to load the server and emits a mcp.digest_mismatch audit event.

Danger

Without pinning, a compromised MCP server could silently change its tool definitions between connections. Always pin production MCP servers.
