Nothing serious here today

Today is the operative word: we check Memra every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

memra

memra_bootstrap

Load agent bootstrap context from Memra. Returns priority-ordered memories for agent session initialization.

memra_get

Get a single memory by ID with full content. Use when you need the complete text of a memory (search results are truncated).

memra_history

View the full supersession chain for a memory (oldest to newest). Use this when you need to audit how a fact or decision evolved over time — e.g., the user asks "why did we change X?", you need to understand prior reasoning before proposing another change, or you spotted a superseded_by reference and need the full timeline. Given any memory ID in the chain, returns every predecessor and successor.

memra_list

List memories in Memra for a namespace. Returns paginated results with filtering options.

memra_recall

Search memories in Memra by semantic similarity. Returns ranked results by relevance. Replaces memra_search.

memra_remember

Store one or many memories in Memra. Single mode: pass content + namespace. Decision mode: pass type=decision with content + namespace (optionally context). Pattern mode: pass type=pattern with title + steps + namespace. Bulk mode: pass entries[]. If the response contains conflicts[], the new fact contradicts those existing memories — review them and use memra_supersede on the outdated one instead of leaving both active.

memra_supersede

Replace a memory with new content. The old memory is marked superseded and stops appearing in search; the new memory inherits the old memory's type, importance, tags, source and metadata unless overridden. Works for all memory types (use this instead of memra_add when you are correcting or updating existing knowledge).

Memra — questions

Answers built from our own checks of this server.

What can Memra do?

It exposes 7 tools, read directly from the server on our last check. Among them: memra_bootstrap, memra_get, memra_history, memra_list, memra_recall, memra_remember and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Memra working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 209 ms. The bar chart above shows every period we have measured.

How do I connect Memra?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Memra need an API key?

No. Memra completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Memra?

It answers our handshake in 209 ms on average, which is faster than 65% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Memra open source?

Yes — it is published under the MIT licence and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
