"LibreOffice Calc" matching MCP servers:

Enables multiple concurrent MCP clients to safely share one backend MCP server by terminating client sessions, serializing forwarded calls, and mirroring the backend's exact tools and schemas. It also reconnects automatically if the backend restarts or drops, exposing a status tool for reachability checks.

Enables deterministic repair of malformed tool-call schemas and guards parameter projections for AI agents, ensuring reliable JSON-RPC interactions via MCP.

Graph-based tool retrieval for LLM agents. Builds a tool graph from OpenAPI/MCP specs and retrieves multi-step workflows via hybrid search (BM25 + graph traversal + embedding), recovering accuracy from 12% to 82% with 79% fewer tokens. Also works as an MCP Proxy to aggregate multiple servers behind 3 meta-tools.
