CoffeeCode builds developer tools for AI-native workflows. Our first product lets agents look up anything that happened across every past session — decisions, changes, bugs, and why things were built the way they were.
Flagship product
coffeectx is a Model Context Protocol server that indexes all your agent session logs into a semantic knowledge graph. In a brand new session, your agent can query the full history of past decisions, bugs, architecture choices, and implementation changes — with no manual context-stuffing required.
Tested with Claude Code. Supports semantic search, regex, and graph-like queries. The knowledge graph is extensible: define new entity types and extraction skills to teach it what matters most to your project.

Three complementary search modes so your agent always finds exactly what it needs.
Ask in plain language. coffeectx understands meaning, not just keywords — so "how was auth designed?" finds every relevant decision even if they used different words.
Pin down exact patterns: function names, error codes, config keys. Fast, precise, and composable with semantic results.
Navigate relationships between decisions, files, bugs, and features. Understand what caused what, and trace the full lineage of any choice.
Define your own entity types and extraction skills. Teach the graph what's important for your domain — deployment targets, experiment IDs, customer names, anything.
Plugs directly into the Model Context Protocol ecosystem. Any MCP-compatible agent can use coffeectx without custom integration code.
Seamless first-party integration with coffeeclaw — giving agents persistent, queryable memory across every session out of the box.
How it works
Point coffeectx at your agent log directory. It reads every session, extracts entities and relationships, and builds an optimized knowledge graph.
Add coffeectx as an MCP server in your agent config. One line of JSON. No API key, no cloud dependency, runs locally.
Your agent can now ask natural-language questions about the entire project history from a fresh session — no manual context loading required.
Open source
coffeectx is open source and free to use. Star the repo, try it with Claude Code, and help shape where it goes next.
