# Update an MCP server

`PUT /api/v0/agent/mcp-servers/{mcp_server_id}`

## Request

- Base URL: `https://api.outerport.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.outerport.com/api/v0/agent/mcp-servers/{mcp_server_id}`
- Auth: HTTP bearer
- TypeScript: <https://skmtc.dev/outerport/apis/outerport-api/docs/api/v0/agent/mcp-servers/:mcp_server_id/put.ts> (a function with typed inputs; its response is checked against the schema)

## Request body

## Response `200`
