marm-mcp-server — Claude Code MCP server: features and setup
This server gives AI agents shared local memory for notes, decisions, and project history. It can also index a repository so agents can find symbols and trace code paths.
claude mcp add marm-mcp-server -- uvx marm-mcp-serverWhat marm-mcp-server does
marm-mcp-server stores conversations, notes, and summaries in local memory that agents can search. It also builds a code graph for a repository, helping agents locate symbols and follow paths through the code. A concept graph links stored decisions, errors, and ideas to relevant code when available.
The server supports HTTP and STDIO, and agents can use the same memory across sessions. To connect it to Claude Code, run claude mcp add marm-mcp-server -- uvx marm-mcp-server. The memory is local, not a remote shared service; the project provides a swarm profile for multiple agents.
What it helps with
- carry decisions and notes between agent sessions
- search stored conversations for past context
- locate symbols and code paths in a repository
- connect stored ideas and errors to project code
Example prompts for the agent
- Save this project decision to shared memory.
- Find the notes about the earlier database connection error.
- Locate this symbol in the repository and trace the code paths that use it.
