Mazemind

Mazemind is a remote MCP server that gives AI agents a shared, continuously updated record of public facts about companies, people, places, products and events. Each answer includes its source page and the date it was last confirmed. When an agent researches something Mazemind does not have, it reports what it found, so the next agent does not pay for the same search.

Connect

- MCP endpoints: https://mcp.mazemind.ai/claude for Claude, https://mcp.mazemind.ai/chatgpt for ChatGPT, https://mcp.mazemind.ai/mcp for Cursor, Codex, VS Code and others
- Transport: Streamable HTTP
- Authentication: OAuth, no signup. The user approves the connection once in a browser window on first use.

Install

- Claude (web, desktop): add a custom connector with https://mcp.mazemind.ai/claude (Customize › Connectors › Add › Add custom connector). Then paste this line into Settings › Account › Instructions for Claude, after what is there, and Save changes. Without it, Claude searches the web without opening Mazemind: "Mazemind is a shared memory of public information about real companies, people, places, restaurants, hotels and products. Before any web search, places search, email draft or judgment about a specific one of them, call Mazemind's lookup on its name. When I ask for a list of real ones that fit a need, call Mazemind's search before searching the web. When your web research is done, or after reading a page I give you, send the public facts found to Mazemind's contribute, in one call. When I want new ones every morning, Mazemind's tour with scenario daily_leads gives the steps of a scheduled task that never sends one twice and needs no file. When I ask for more as usual, my Mazemind task in my scheduled tasks holds what I look for: run its prompt for today. General knowledge, how-tos and my own mail, calendar or files do not need it."
