Runtime

MCP servers in a sandbox

runtime sandbox mcp and sbx.mcp start GitHub, Postgres, a Playwright browser, filesystem, fetch and nine more MCP servers in a sandbox in one call, each at an authenticated URL your agent connects to; secret settings come from Runtime secrets, so the server never holds the value. GET /v1/mcp/catalog lists them with their licences.
