"Relay" matching MCP servers:

An AI operations agent that reads from your own PostgreSQL database and policy documents, provides grounded answers with citations, and exposes read-only tools to external MCP clients while keeping writes behind a human approval gate.

160 tools that do that heavy lifting - storage, agent-to-agent collaboration, document conversions, identity verification -- almost all priced under a tenth of a cent or less per call.

Enables efficient AI workflow orchestration by chaining multi-step LLM operations while keeping intermediate results out of the context window, reducing token usage by 90%+ and supporting multiple AI providers.

MCP server that exposes hardware automation tools (build, flash, serial capture, symbolization, relay control) for ESP32-S3 boards, with board-level concurrency locks and remote access.
