Connect AI tools (MCP)

Assyro's MCP server lets an AI tool search the regulatory and FDA sources Assyro holds and ask Assyro research questions, answered with citations. The server is https://mcp.assyro.com/mcp (Streamable HTTP). You sign in with your Assyro Intelligence account, or use an API key.

Quick start

Install in one click, or paste this prompt into Claude Code, Codex, Cursor or any agent: it adds the server and tells you how to sign in.

Connect me to Assyro's MCP server, https://mcp.assyro.com/mcp (Streamable HTTP, sign-in with OAuth).
- Claude Code: run `claude mcp add --transport http assyro https://mcp.assyro.com/mcp`, then tell me to run /mcp and choose Authenticate.
- Codex: add [mcp_servers.assyro] with url = "https://mcp.assyro.com/mcp" to ~/.codex/config.toml, then run `codex mcp login assyro`.
- Cursor: add "assyro": { "url": "https://mcp.assyro.com/mcp" } under mcpServers in ~/.cursor/mcp.json, then tell me to choose Connect in Cursor Settings, MCP.
- If I give you an API key instead, send it as the header "Authorization: Bearer <key>"; never write the key into a file I commit.
Then read https://www.assyro.com/docs/llms.txt for the tools (search, get_record, ask_assyro, list_workspaces) and use them to answer my regulatory questions with citations.
