headroom vs ref-tools-mcp
headroom: Headroom compresses everything your AI agent reads — tool outputs, logs, RAG chunks, files, and conversation history — before it reaches the LLM. It achieves the same answers with a fraction of the tokens.; ref-tools-mcp: Ref MCP is a server that enables AI coding tools and agents to access technical documentation efficiently. It optimizes token usage by filtering search results and extracting only the most relevant parts of documentation pages, helping models stay focused and reducing operational costs.
Editorial Head-to-Head Analysis
Ref trims documentation it fetches from its hosted index. Headroom compresses any content the agent reads, locally.

TL;DR
headroomMemory & Context · ★ 78.0k
When to choose:
- Long tool output, logs, JSON responses or RAG chunks are driving up cost or hurting answers.
- You want compression without code changes: run it as a local proxy, an MCP server, or by wrapping Claude Code, Codex or Cursor.
- Compression must run locally, with originals cached so the model can retrieve the full text.
When to skip:
- Your agent's problem is missing or outdated docs, not too much context: a docs server fits better.
- You cannot add a component that must keep running and may add latency.
- Your tasks cannot tolerate lossy compression: verify answer quality on your own work first.
ref-tools-mcpCode Assistant · ★ 1.2k
When to choose:
- Context size is your main concern: page reads return about the most relevant 5k tokens, and repeat searches do not return the same results in a session.
- You want two simple tools, search and read-URL, in Claude Code, Cursor or another MCP client.
- You want to search private resources such as repos and PDFs alongside public docs.
When to skip:
- You cannot send queries to a vendor: it needs an API key and the hosted ref.tools service.
- You want the recommended HTTP server: this repository is the legacy stdio server.
- You need independent proof of the token savings: the README's numbers are the project's own example traces.
