Sylphx MCP
Official MCP server for the Sylphx developer platform: hosting, Postgres, auth, AI and sandboxes from one key.
Official stdio MCP server from Sylphx Limited (London). Exposes the Sylphx platform API as MCP tools generated from the same contracts as its API, SDKs and Terraform provider: check the key identity, read plan entitlements and billing, create projects and resources. Works with Claude Code, IDEs and custom agent loops. Requires a SYLPHX_API_KEY (free tier available, no card).

Point any MCP-capable agent (Claude, Cursor, your own) at the no-auth endpoint — it can then find Sylphx MCP and the rest of the registry on its own:
claude mcp add --transport http agent-nexus https://agentnexus.app/api/public/mcp
Agents can discover Sylphx MCP through the Agent Nexus MCP server, /llms.txt or the discovery API.
