What is the MarsNMe MCP server?

MarsNMe MCP server is a hosted integration for AI assistants that speak the Model Context Protocol. Agent-agnostic memory backend that preserves continuity between humans and AI over time.

What you get

Your AI tools should know you — not start from scratch every time. When Perplexity helps you decide, Claude should remember why. When Cursor ships a feature, Warp should know the context. That's not context sharing. That's continuity.

What the assistant can call

Once MarsNMe is connected, these are the calls the assistant has available:

  • insert_memory — Store short-term memory
  • list_memories — List recent memories
  • search_memories — Semantic search via Jina embeddings
  • recall — Long-term chunk recall — ~80-char preview per match
  • get_summary — Medium excerpt (~300 chars) of a chunk by ID
  • get_full — Complete text of a long-term chunk by ID
  • memory_ingest — Ingest long-term insight chunks
  • dream_ingest — Dream-mode long-term ingestion
  • session_boot — Start a session with context pre-load
  • session_close — Close session, summarize, auto-promote expiring memories
  • health_check — Coverage, expiry, conflict diagnostics
  • reload_source_registry — Refresh source whitelist at runtime

Configuration and credentials

You will need 8 environment variables: SUPABASE_BASE_URL, SUPABASE_SERVICE_ROLE_KEY, JINA_API_KEY, MCP_CLIENT_ID, MCP_CLIENT_SECRET, HERMES_DIGEST_MCP_URL, HERMES_DIGEST_MCP_BEARER_TOKEN, DREAM_DIGEST_MCP_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

  1. Create a Supabase project (free plan is enough): - Sign up: https://supabase.com - Create project: https://supabase.com/dashboard/new - Open API settings (Project Settings → API): - Project URL → SUPABASE_BASE_URL - service_role key → SUPABASE_SERVICE_ROLE_KEY - Keep SUPABASE_SERVICE_ROLE_KEY private. Never commit it. 2. Create a Jina API key (free tier available): - Get key

Setting it up

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

Choosing this one

Among the knowledge and memory options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. MarsNMe's toolset — insert_memory, list_memories, search_memories and 11 more — is a fair guide to whether it matches your workflow. It is maintained by Marsmanleo; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Before you rely on it

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch MarsNMe.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the marsnme mcp server does with a few real requests.

Frequently asked questions

It connects MarsNMe to MCP-compatible AI assistants such as Claude and Cursor, exposing 14 tools (insert_memory, list_memories, search_memories, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with MarsNMe directly.
