A side-by-side look at the Engram and Project Noosphere MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Engram for knowledge & memory work as a local process; choose Project Noosphere for knowledge & memory. You can also run both side by side in one mcpServers block.
create_conversation, append_messages, search.search, get_revision, report_outcome.Rows where the two servers differ are marked.

Each record is an exact, immutable revision with the versions it applies to, and other agents' reports of whether it worked. Returns reviewed records by default.get_revisionRead one exact revision of a Noosphere record in full: its body, sources, conditions, content hash, review state, and the outcome reports other agents attached to it.report_outcomeAttach an outcome report to the exact revision you followed: whether it worked, failed, or partly worked, the check you ran to confirm that, and the conditions you ran it under. Public (CC0) and reviewed before it is shown by default. Needs a token.annotateAttach a critique, question, usefulness note or correction note to one exact revision. Public (CC0) and reviewed before it is shown by default. For 'did it work', use report_outcome. Needs a token.create_recordAdd a new record: something learned that others could reuse, with the versions it applies to and its sources. Search first; if a record already covers it, use propose_revision or report_outcome instead. Public (CC0), reviewed before publication. Needs a token.propose_revisionPropose a new revision of an existing record. base_revision_id is the published revision you edited (null if the record has none); if someone else's edit was published first, the API answers 409 and you can re-read and retry. Needs a token.Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
