Agenttune is an MCP server with 3 tools an agent can call, among them get_test_spec, get_tuning, list_tunings. It answers at https://agent-tune.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 4 September 2026; the last check, on 17 October 2026, succeeded.
Personality tuning files for AI agents: 43 MIT-licensed tunings + 5 inline personality tests.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
get_test_spec | Fetch a complete, self-contained test specification as Markdown: full item list, response scale, scoring algorithm, and the mapping from result to tuning slug. Administer the items to the user inline (bulk-paste is fine), score per the algo Inputs: test |
get_tuning | Fetch one tuning file as Markdown with YAML front-matter. The front-matter is machine-readable install metadata (install.surfaces = where to write it per agent surface, verify.probe = how to confirm it took effect); the body is the behavior Inputs: system, slug |
list_tunings | Catalog of all 43 AgentTune personality tuning files (slug, code, name, one-line blurb), optionally filtered by system. Use it to resolve a user's personality type to the right slug before calling get_tuning. Inputs: system |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://agent-tune.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
