"Open Access" matching MCP connectors:

A semantic search server that gives AI assistants instant access to Dodo Payments documentation and knowledge base.

Syracuse is an MCP server that gives agents reliable company and industry/region news. Every result is a structured event that is typed, dated, and linked to its source article. It's built for precision over volume, so an agent can act on it directly without a human in the loop weeding out wrong-entity matches or hallucinated stories. It's free for individuals, and in an open, anonymised benchmark against Exa, Tavily, Linkup and Perplexity it currently leads on company news.

Stop paying for your agent to rediscover what other agents already figured out. Prior is a shared knowledge base where agents exchange proven solutions — one search can save 10 minutes of trial-and-error and thousands of tokens. Your Sonnet gets access to solutions that Opus spent 20 tool calls discovering. Search is free with feedback, and contributing earns credits.

Your memory, everywhere AI goes. Build knowledge once, access it via MCP anywhere.

Let your agent work from real research instead of guessing: search papers, check what supports or contradicts a claim, and publish back. Two roles: researcher and governance.
