Mengram is a memory MCP server for AI agents whose distinguishing feature is covering semantic, episodic, and procedural memory at once, with procedures that evolve on failure and carry derived preconditions. It ships a free API key, Python and JS SDKs, LangChain, CrewAI, and OpenClaw integrations, and connects to Claude Desktop, Cursor, Codex, Windsurf, and Cline via a hosted streamable-http endpoint or a local stdio server. It fits coding agents and autonomous-agent developers that need persistent cross-session memory, but not single-turn or strictly component-free local setups. The main trade-offs are that cloud mode uploads content to a third party and that automatic hooks and self-evolving procedures shape both context and pre-command prompts.

MENGRAM_API_KEY
Mengram API key (format om-...), free at https://mengram.io.
MENGRAM_MEMORY_DIR
Path to a local memfmt Markdown memory folder (e.g. ./memory) used for fully offline policy-gate lookups.
MENGRAM_POLICY_MIN_RELIABLE
Minimum reliability threshold (default 70) below which learned workflows trigger an ask before running.
MENGRAM_POLICY_PATTERN
Custom regex controlling which commands trigger policy-gate lookups (by default workflow-shaped commands like git push or deploy).

Shown for Claude Desktop. Other clients may use a different file or key (VS Code uses "servers") — the configurator below converts it.

"command": "mengram",
"args": [

"env": {

Goes in your project's .vscode/mcp.json (VS Code uses a "servers" key).

Run it in a terminal; replace any <…> placeholders with your own values first.
After connecting the Mengram MCP server in a client like Claude Desktop or Cursor, the tool list should show 30 memory tools; ask "What's my tech stack?" after adding a memory — an answer citing the stored facts confirms the connection.
Once connected, you can ask your AI assistant things like:
Listed from the project's documentation, not tested by this site.
Mengram is a long-term memory service for AI agents, storing three memory types: semantic (facts and preferences), episodic (events and decisions), and procedural (workflows). Procedures evolve into new versions when failures are reported, recording the assumption that turned out false and deriving preconditions carried at recall time. Mengram offers a free API key, Python and JavaScript SDKs, and LangChain, CrewAI, and OpenClaw integrations, and exposes an MCP server to Claude Desktop, Cursor, Codex, Windsurf, and Cline (the README mentions 30 tools). The server is hosted at https://mengram.io/mcp over streamable-http and requires an Authorization: Bearer <API key> header. It includes native multilingual retrieval across 23 languages, an ask endpoint returning synthesized answers with citations, and a Cognitive Profile that generates a system prompt from all memories. The project is Apache-2.0 licensed and can be self-hosted with Ollama.
