概览

What is Memra?

Memra is a remote MCP (Model Context Protocol) server providing persistent memory for AI agents, hosted in Helsinki (EU). It offers privacy-first, deterministic recall in under 100ms with no LLM in the hot path, and has a free tier with no credit card requirement.

How to use Memra?

Obtain an API key at usememra.com, then configure Memra as an MCP server in your client. For Claude Code use claude mcp add --transport http memra https://usememra.com/mcp --header "Authorization: Bearer memra_live_YOUR_KEY". For Cursor, Cline, or any MCP client, add the endpoint and auth header to your mcp.json file.

Key features of Memra

memra_remember / memra_recall for storing and retrieving facts with hybrid semantic + lexical search
Write-time contradiction detection: storing a conflicting fact returns conflicts[]
Read-your-writes with revision tokens and wait_for_revision for deterministic recall
memra_supersede and memra_history for full audit trails when memories are retired
Staleness signals (staleness_score / last_confirmed) on every result
Token-budget recall via max_tokens to fit context windows
memra_bootstrap for priority context at session start
Multi-tenant namespaces, PII masking (7 EU languages), and read-only scoped keys

Use cases of Memra

Give AI agents persistent memory that survives across conversations and sessions
Detect and resolve contradictory facts during storage (e.g., outdated user preferences)
Retrieve facts exactly matching identifiers, error codes, or semantics within a token budget
Manage memory lifecycle with explicit superseding and history for audit purposes
Provide priority context at the start of each session via bootstrap
