Audits MCP tool descriptions for quality and reliability, scoring them 0-100, detecting smells, and providing rewritten versions for better agent accuracy.
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.
Provides semantic memory and persistent storage for Claude, leveraging ChromaDB and sentence transformers for enhanced search and retrieval capabilities.
A TypeScript-based Model Context Protocol server that integrates with Volcengine's Jimeng AI image generation service, allowing users to generate AI images through simple tool calls.
gmail-mcp is a remote MCP server that exposes Gmail as a set of tools — search, read, label, draft, send — over streamable HTTP with OAuth 2.1. It runs on Cloudflare Workers under your own domain.
Provides a 1-line USDC paywall wrapper for any FastMCP tool using the Coinbase x402 protocol, enabling pay-per-call endpoints settled on Base, Polygon, Solana, or Bitcoin Lightning.
Real-time hydrological information retrieval service that provides water level, precipitation, dam discharge data, and observatory location information.
MCP server that detects and guards against tool poisoning and prompt injection attacks in tool descriptions and schemas. It provides risk scoring, pattern detection, safe rewriting, and audit reports with zero external API cost.
Serves a strictly read-only mail archive over MCP: ordered filter rules pull matching messages from any IMAP mailbox or the Gmail API and write them to disk as byte-faithful .eml plus markdown with YAML frontmatter. Exposes list_rules, list_messages, search_messages, read_message (with full-thread reads) and sync; it never sends, deletes or modifies mail.
