Curated by Archimedes Market with a verified Trust Report. Expose any LangChain chain, agent, or tool as an MCP server. Schema-aware tool registration, tool-call tracing, retry/timeout policies, structured output validation. Bridges the LangChain ecosystem into Claude / ChatGPT / Cursor without rewrites. → archimedes.market/assets/312e3c99-f858-44e7-ba2c-fcaf408825a8.

Named after the Q-signal QSP ("Will you relay?"), qsp-mcp relays tool calls between a local LLM and MCP servers. Any model with function calling capability gains access to the full qso-graph tool ecosystem — 71+ tools across 12 servers — from local weights, not from cloud.

The JustCall Model Context Protocol (MCP) Server lets Large Language Models (LLMs) and AI agents make real-world voice calls and send SMS directly through JustCall’s APIs — securely, contextually, and programmatically. It provides a function-calling interface for conversational AI systems, enabling: 📞 AI-powered calling: Let your LLM initiate, manage, or transcribe calls using JustCall. 💬 Smart messaging: Allow your AI agent to send or respond to SMS within conversations. ⚙️ Seamless integration: Use the MCP standard to connect JustCall’s telephony capabilities with any LLM runtime or orchestration framework. In short: It gives your LLMs a voice and a phone number — turning chatbots into truly conversational agents.
