Cortex vs headroom
Cortex: Cortex is an MCP server that gives Claude Code persistent memory inspired by neuroscience. It automatically captures, consolidates, and surfaces relevant context, achieving state-of-the-art retrieval benchmarks across multiple datasets.; 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.

TL;DR
CortexMemory & Context · ★ 75
Long-term project memory and context retention across sessions
headroomMemory & Context · ★ 77.5k
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- Your agent's problem is missing or outdated docs, not too much context: a docs server fits better.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.
