Questions
What is the MARM MCP server?
Local-first 3-in-1 AI memory layer & MCP server for Claude Code, Codex, Grok, Gemini, VS Code and Cursor. Fuses session history, codebase indexing & concept graphs in SQLite. Enables zero-cloud, privacy-first context & instant recall, supports multi-agent swarms.
What tools does MARM expose?
11 in total: 11 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is MARM safe to connect to an agent?
No — not without reading the findings first. The audit graded it F (47/100) and found 5 critical or high issues in the source. Each one is listed on this page with the file and line it is on.
What credentials does MARM need?
It reads MARM_API_KEY, MARM_GRAPH_API_KEY and MARM_LLM_MAX_RETRY_TOKENS from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does MARM run?
It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as workspace at 2.57.0.
How current is this page?
The grade is for one exact copy of the source (26a87365e60f), read on 2026-10-03. The repository is watched and re-audited when it changes.
