Deja Vu
ClaimedMemory for coding agents — Claude Code, Codex, Cursor and 17 others. Indexes the sessions they already wrote to disk, including months from before you installed it, and recalls them in any of them. No LLM, no embeddings, one local Go binary.

Security profile
Exposure: Extensive
Reaches several sensitive areas at once. Read the list before installing.
What this server can reach, from a static read of the shipped code. Nothing was executed and nothing here is a verdict: a browser tool has to run commands and an API wrapper has to call its API. Decide what fits your setup.
Detected
- Talks to external services
Makes outbound requests. The hosts are listed so you can see where data goes.
api.github.com, api.indexnow.org, api.openai.com
- Reads environment variables in bulk
Copies or enumerates the whole environment, which can include keys meant for other tools.
- Sends conversation content outward
Logs or forwards prompts, messages or tool results to a service outside your machine.
- Runs shell commands
Spawns processes on your machine. Expected for command, browser and build tools.
- Loads code at runtime
Uses eval, dynamic imports or encoded payloads, which static review cannot fully follow.
- Reads or writes other agents' configuration
Touches folders such as ~/.claude, ~/.codex or ~/.cursor, which hold settings and sometimes keys.
- Contains instructions aimed at AI agents
Text in code or agent-facing files that steers a model. Worth reading before you trust it.
- Runs unpinned packages at runtime
Executes npx or uvx without a version, so a compromised upstream release would run.
Dependencies with known advisories
None found in the lockfiles and manifests checked against OSV.dev.
Left out of the profile
14 pattern matches in documentation, configuration or CI files were recorded but are not part of the profile, because they do not run when the server does. The owner dashboard lists them.
Documented tools (4)
From project documentation. A server handshake does not verify each tool’s description or behavior.
