How do I install the a mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `LLM_BACKEND`, `LLM_MODEL`, `OPENAI_API_KEY`, `CHROMA_DB_PATH`, `OPENROUTER_API_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the A MCP Server?

Self-evolving memory system for AI agents

What you get

A-MEM is a self-evolving memory system for coding agents. Unlike simple vector stores, A-MEM automatically organizes knowledge into a Zettelkasten-style graph with dynamic relationships. Memories don't just get stored—they evolve and connect over time.

Recorded tools

Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.

Tool	What it does
add_memory_note	Store new knowledge (async, returns immediately)
search_memories	Semantic search across all memories
search_memories_agentic	Search + follow graph connections
search_memories_by_time	Search within a time range
read_memory_note	Get full details (supports bulk reads)
update_memory_note	Modify existing memory
delete_memory_note	Remove a memory
check_task_status	Check async task completion
