A Show HN MCP Proxy Puts Policy Where the Model Cannot Reach It
Sente Labs posted extensible-mcp on September 1, an Apache 2.0 proxy sitting between an LLM and its MCP servers that does on-demand server loading, searchable tool discovery and pluggable access-control filters, with the policy layer deliberately outside the model's reach. The repo has 4 stars and was created 2026-06-11, so this is one data point rather than a movement, but it is the same governance-wrapper shape that dominated Show HN through late August. Paired with MCPbeat's finding that 2,326 registry-listed servers never answer, the MCP layer is now generating its own tooling market for trust and liveness.
