Protologue — Claude Code MCP server: features and setup
Connect an agent to a sourced taxonomy of prompting and LLM techniques. Use it to look up a method, see how terms relate, and find primary sources.
claude mcp add --transport http protologue https://mcp.protologue.com/mcpWhat Protologue does
Protologue is a reference taxonomy for prompting and LLM techniques. Its entries provide standalone definitions, alternate names, links between concepts, and primary sources. The MCP server makes this reference available to Claude Code, Codex, Cursor, and the other listed platforms.
The server runs as a Cloudflare Worker at https://mcp.protologue.com/mcp. Ask an agent to explain a technique, trace its links to related terms, or identify its sources. Benchmark entries cover what a benchmark measures, its scoring setup, and its limitations; they leave out scores and rankings. For Codex, connect it with codex mcp add mcp --url https://mcp.protologue.com/mcp.
What it helps with
- look up a prompting technique’s definition
- trace links between LLM methods
- find primary sources for a term
- check what a benchmark measures and where its limits lie
Example prompts for the agent
- Find the definition of self-consistency and list its primary sources.
- Explain how chain-of-thought relates to other techniques.
- What does this benchmark measure, and what limitations does its entry describe?
