Known publicly hosted MCP endpoints and how to configure them as mcpproxy backends, grouped by outbound auth mode. Ready-to-run configs sit next to this file.
Before you pick one:
- Both remote transports work: streamable-HTTP
(
transport: streamable-http) and the legacy HTTP+SSE protocol (transport: sse). Entries marked ⚠ below needtransport: sse. - All of these ship in the built-in catalog (
catalog/catalog.yaml):import-catalog -listshows them,import-catalog linear stripe …emits ready-made backend stanzas.-catalog <file>loads a custom YAML catalog with the same schema;-dir <dir>imports from a tree of MCP-registryserver.jsonfiles. auth: oauthendpoints run discovery + dynamic client registration + PKCE; the daemon prints the authorize URL on first use. Many of these providers also issue static tokens (PATs) usable withauth: static.- URLs change. Check the provider's docs if a probe returns 404.

Config: oauth.yaml
aggregated.yaml fronts several remotes behind one
endpoint with per-backend policy, giving your team one URL for everything.
Marketing calls some well-known projects "MCP servers" when they expose no
remote endpoint. Figma's Dev Mode MCP runs locally inside the desktop app,
so configure http://127.0.0.1:3845/mcp as a streamable-http backend.
Most community servers (filesystem, git, fetch…) ship as stdio packages;
see the top-level examples for those.
