Gnosem MCP server

Gnosem is a remote MCP server that gives an AI agent 6 tools, among them memory_forget, memory_list, memory_search. It answers at https://gnosem.dev/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, succeeded.

Cross-vendor AI memory over MCP. One semantic store, readable and writeable from every MCP client.

Description as the publisher wrote it.

The 6 tools Gnosem offers

Tool	What it does
`memory_forget`	Soft-delete a memory by id. The row is retained for audit but excluded from search/list and removed from the vector index. Inputs: id
`memory_list`	List the user's most recent memories in reverse chronological order. Use for browsing or catching up on what the user's other model sessions have written recently. Same content/content_raw shape as memory_search. Optional filters (tags, wri Inputs: limit, cursor, raw, tags, written_by, session_id
`memory_search`	Search the user's memories. Default mode is 'hybrid': blends semantic (cosine over Vectorize) and keyword (BM25 over SQLite FTS5) hits via Reciprocal Rank Fusion (k=60). Semantic catches paraphrases; keyword catches exact-string hits (IDs, Inputs: query, k, mode, raw, tags, written_by
`memory_supersede`	Replace a stale memory with a corrected one. The old row is marked superseded and excluded from future reads; the new row becomes the current version. Use for corrections; use memory_forget for pure deletions. Inputs: old_id, new_content, tags, written_by, session_id
`memory_write`	Save a fact, preference, decision, or note to the user's cross-model memory. Any MCP client can read this back later. Include written_by (e.g. 'claude-code', 'gpt-5', 'kimi-k2') for provenance and session_id to group related writes. Long co Inputs: content, tags, written_by, session_id, no_optimize, force
`memory_write_bulk`	Write up to 50 memories in a single call. Each entry runs the same path as memory_write (semantic dedup by default; pass force:true per-entry to skip). Embeddings + optimizations run in parallel; D1 inserts are batched. Returns { results: [ Inputs: memories

6, as returned by the server's own tools/list on 11 September 2026: memory_forget, memory_list, memory_search, memory_supersede, memory_write, memory_write_bulk.

Is Gnosem down?

It answered our last check on 19 October 2026 in 171 ms. Over 6 checks since 10 September 2026 it answered 6.

How do I add Gnosem to Cursor?

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://gnosem.dev/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.

Does Gnosem need an API key?

It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

Where this comes from

Publisher: dev.gnosem. Endpoint host: gnosem.dev. ARD identifier: urn:air:dev.gnosem:mcp:gnosem. First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page is inferred from its name. Ranking in Neuronto search is never for sale.
