memra — Claude Code MCP server: what it does, how to install
Remote long-term memory server for AI agents with hybrid retrieval, write-time conflict detection, and EU hosting.
claude mcp add --transport http memra https://usememra.com/mcpWhat memra does
The server keeps project conventions, technical decisions, and context across separate agent runs. It combines vector semantics with BM25 keyword matching, which helps agents look up exact error messages or variable names. When storing a new observation, the service spots clashes against existing records and flags conflicts so the agent can retire superseded facts.
Calls go to the remote HTTP endpoint at https://usememra.com/mcp. You need an API token from usememra.com before connecting your client. Infrastructure runs in Helsinki and includes PII masking across seven European languages. Teams seeking a self-contained setup can run the offline memra-local package with SQLite and ONNX embeddings.
What it helps with
- keep architectural decisions across independent agent sessions
- locate exact symbol names and error codes with BM25 hybrid lookup
- detect contradicting statements before saving new records
- fit retrieved context into a strict token budget
Example prompts for the agent
- Remember that we enforce strict input validation on all auth endpoints
- Recall our decisions regarding database migrations and foreign key constraints
- Check memory for the error code ERR_PAYMENT_TIMEOUT and show its history

How to install memra in Claude Code?
Run claude mcp add --transport http memra https://usememra.com/mcp. You will also need to pass your authorization token in the request header.
What does memra do?
It provides persistent external memory for AI coding agents. The server stores facts, surfaces conflicting information on write, and retrieves past context using lexical and semantic search.
Is an internet connection required to use memra?
The primary MCP server connects to https://usememra.com/mcp and requires an API key. For environments without web access, you can run memra-local using SQLite and local ONNX models.
