Overview

Memra MCP Server

Persistent memory for AI agents — remote MCP server. EU-hosted (Helsinki), privacy-first, deterministic sub-100ms recall with no LLM in the hot path.

Endpoint: https://usememra.com/mcp (Streamable HTTP) · Registry: com.usememra/memra · Free tier, no credit card.

What it gives your agent

memra_remember / memra_recall — store facts, decisions, patterns; hybrid semantic + lexical (BM25) search that also matches exact identifiers and error codes
Write-time contradiction detection — storing a fact that clashes with existing knowledge returns conflicts[] so the agent can supersede the outdated one
Read-your-writes — every write returns a revision token; recall with wait_for_revision is deterministic
memra_supersede + memra_history — memories retire with full audit chains instead of going stale
Staleness signals — every result carries staleness_score / last_confirmed; the agent decides what to trust
Token-budget recall — max_tokens: 2000 returns the best memories that fit your context window
memra_bootstrap — priority context at session start
Multi-tenant namespaces, PII masking (7 EU language models), read-only scoped keys for subagents
