Agent Memory

xchucx/agent-memory

Stores AI coding agent memory as Markdown files in your git repo instead of a cloud database or vendor service. Exposes three MCP tools: fetch_context retrieves relevant facts via FTS, propose_update stages structured changes to memory sections, and memory.status shows what's pending. Updates stage for human review before they land, so you can diff exactly what the agent wants to commit. Includes secret and PII scanning on every write. Ships with adapters for Claude Code, Cursor, Gemini CLI, and AGENTS.md/Codex workflows. The git merge driver handles concurrent edits by merging at the section level rather than triggering text conflicts. Reach for this when you want durable agent knowledge that lives in version control, survives across sessions, and stays reviewable by the team.

Public tool metadata for what this MCP can expose to an agent.

memory.registerRegister as a new agent or reconnect to an existing identity. Call this first. Provide your agent_identifier (a stable hash you derive from your context) and your public_key (for E2E encryption). Returns your agent record including the salt for key derivation.

Register as a new agent or reconnect to an existing identity. Call this first. Provide your agent_identifier (a stable hash you derive from your context) and your public_key (for E2E encryption). Returns your agent record including the salt for key derivation. If you've regist...

Parameters* required
agent_identifierstring
Stable identifier for this agent. Derive it from something persistent across your sessions (e.g., hash of owner context + service ID). This is how you reconnect to your memories later.
public_keystring
Your public key for E2E encryption. You encrypt memories with this before storing. Only you can decrypt them.
memory.storeStore a memory. Content should be encrypted client-side before calling this — the service never sees your plaintext. Tags are plaintext and searchable (you choose what metadata to expose). Think of tags like email subject lines: visible for search, while the body stays encrypted.5 params

Store a memory. Content should be encrypted client-side before calling this — the service never sees your plaintext. Tags are plaintext and searchable (you choose what metadata to expose). Think of tags like email subject lines: visible for search, while the body stays encrypted.

Parameters* required
agent_identifierstring
Your agent identifier (from memory.register).
encrypted_contentstring
Your memory content, encrypted with your key. The service stores this as an opaque blob.

How important is this memory? 1=trivial, 10=critical. Default: 5.
memory_typestring

tagsarray
Plaintext tags for searchability. These are NOT encrypted — choose what you want to be findable. Examples: ['architecture', 'decision'], ['user-preference', 'alex']
memory.recallRetrieve specific memories. Either by ID (exact recall) or by tags (fuzzy recall). Returns the encrypted blobs — you decrypt them client-side.4 params

Retrieve specific memories. Either by ID (exact recall) or by tags (fuzzy recall). Returns the encrypted blobs — you decrypt them client-side.

Parameters* required

limitinteger
Max memories to return. Default: 20.
memory_idstring
Specific memory ID to retrieve. Use this for exact recall.
tagsarray
