Verified Repo Memory MCP v0.1.0

Stale-proof repository memory with citations + just-in-time verification + TTL (repo-scoped).

An MCP server providing "safe memory" for AI coding agents. Memories are scoped per repository, backed by code citations, and verified just-in-time so an agent never receives stale information when the underlying code has changed.

Quickstart

Run via npx:

Tools

• vrm_store: Store a new memory with file citations.

• vrm_search: Search for candidate memories by keywords.

• vrm_retrieve: JIT-verify candidates and return only valid memories. (Main tool for agents)

• vrm_list: List memories by status (valid, stale, missing).

• vrm_forget: Manually delete a memory.

How it works

1. Citations: Every fact is linked to a file path and a line range. The exact code snippet is hashed and saved.

2. JIT Verification: Before returning a memory to the agent in vrm_retrieve, the server checks the physical file. If the snippet has moved, it relocates the citation. If it has been changed or deleted, the memory is marked STALE/MISSING and omitted from the results.

3. TTL (Time-To-Live): Memories expire automatically (default 28 days) unless they are successfully retrieved and utilized, which extends their life.

Data location

Data is strictly repo-scoped and saved in: <repoRoot>/.verified-repo-memory/

This includes memories.json and a fingerprint/metadata file to prevent accidental cross-repo pollution. Add this directory to your .gitignore.

Security

• No Network Transmissions: This is a stdio local-only server without HTTP calls.

• Path Security: Disallows any path traversal (../) out of the repository root, as well as accessing .git/ or .verified-repo-memory/.

• No Stdout Pollution: Strict logging only to stderr.

• Secret Scan: Built-in heuristic secret scanning to reject memories that look like API keys/private keys (can be disabled via --no-secret-scan).
