MarsNMe

Agent-agnostic persistent memory backend. 13 MCP tools, Supabase + Jina embeddings, multi-profile isolation, semantic recall across sessions.

marsnme.com — Turn your AI into a true companion that never forgets you, never abandons you, and grows with you over time.

Most AI memory tools help AI remember you. MarsNMe helps you and your AI remember each other.

MarsNMe is built on a symbiosis philosophy: shared memory should strengthen trust and continuity between humans and AI over time, not just improve one-off prompts.

An agent-agnostic, LLM-agnostic memory backend for MCP-compatible tools.

When MarsNMe is the right fit

  • You use multiple AI assistants (Claude, Cursor, Warp, custom agents) and want shared memory across all of them
  • You want AI that remembers your projects, preferences, and decisions across sessions without re-explaining
  • You care about data sovereignty — your memories stay in your own Supabase project
  • You're building an AI agent and need a production-ready memory backend with semantic recall

When it might not be the right fit

  • You only need single-session context (just use the system prompt)
  • You want fully managed, zero-config memory with no setup (try a hosted solution)

Before You Start (External Dependencies)

  1. Create a Supabase project (free plan is enough):
  2. Create a Jina API key (free tier available):

Quick Start (15-20 minutes)

This is the fastest first-run path.
It follows the same tools-first flow as docs/onboarding-a-mcp-zero-to-recall.md and docs/onboarding-b-platform-skill-install.md.

  1. Clone repository:
git clone https://github.com/Marsmanleo/MarsNMe.git
cd MarsNMe
  1. Verify Node.js version (20+ required):
node --version
  1. Copy environment template:
cp .env.example .env
  1. Fill required values in .env:
    • SUPABASE_BASE_URL
    • SUPABASE_SERVICE_ROLE_KEY
    • JINA_API_KEY
  2. Run required Supabase migrations before first start:
    • Option A (recommended, Supabase CLI):
npx supabase db push --db-url "<your-supabase-db-connection-string>"
  • Note: --db-url must be the Postgres database connection string from Project Settings → Database → Connection string.
  • It is not the same as SUPABASE_BASE_URL (https://<project-ref>.supabase.co, REST API URL).
  • Use a role that can execute DDL on your target schemas.
  • On Supabase-hosted Postgres this is typically supabase_admin (not postgres).
  • Option B (Supabase Dashboard SQL Editor):
    1. Open SQL Editor.
    2. Ensure the vector extension is enabled first (Database → Extensions).
    3. Run migration files in filename order from supabase/migrations/:
      • 20260504052744_semantic_vector_dual_profile.sql
      • 20260513213800_memory_lifecycle_tracking.sql
      • 20260513222500_health_check_detect_conflicts_v2.sql
      • 20260517183000_provenance_audit_trail.sql
      • 20260517194000_memory_scope_agent_body_environment.sql
      • 20260517200500_forget_demote_mechanism.sql
      • 20260517223500_usage_cost_telemetry_light.sql
      • 20260517231000_memories_source_constraint_regex.sql
      • 20260517232000_source_registry_table.sql
  1. Start gateway:
    • MCP_PROFILE separates memory by agent or use case.
    • Use any profile name you want (for example: default, my-agent, profile-a).
    • Legacy built-in profile IDs coco and toto are still supported for compatibility.
    • If PORT is omitted, default port is profile-based (coco=18790, toto=18791, other profiles deterministic in 20000-29999).
MCP_PROFILE=profile-a PORT=18790 npx @marsnme/mcp-gateway
  1. Verify health:
curl -sS http://127.0.0.1:18790/health
  1. Connect your MCP client (next section), then run the first round-trip check.

Try In 30 Seconds (Docker, M1)

If you only want a local demo path, use Docker Compose.

  1. Set only the required key:
cp .env.example .env
# fill JINA_API_KEY in .env
  1. Start local stack:
docker compose up

This starts:

  • PostgreSQL + pgvector
  • SQL migrations from supabase/migrations/
  • PostgREST + rest-proxy
  • MarsNMe gateway (http://127.0.0.1:18790/mcp)
  1. Verify health:
curl -sS http://127.0.0.1:18790/health

M2 Cloudflare Tunnel Profile (Demo)

When you need a temporary public endpoint for remote AI tools:

docker compose --profile tunnel up

Expected output (from tunnel logs):

https://xxxx.trycloudflare.com

Get MCP endpoint:

docker compose --profile tunnel logs tunnel | grep -Eo 'https://[^ ]+trycloudflare.com' | head -n1
# append /mcp

Notes:

  • trycloudflare.com URL is temporary (demo only).
  • Local endpoint remains: http://127.0.0.1:18790/mcp.
  • For production/stable URL, use named tunnel (outside M2 scope).
  • Optional env:
    • MCP_TUNNEL_PROFILE (default coco)
    • MCP_TUNNEL_REQUIRE_BEARER (default false for demo convenience)

MCP Client Connection Guide

Local endpoint:

  • http://127.0.0.1:18790/mcp

If bearer auth is enabled (MCP_REQUIRE_BEARER=true), include:

  • Authorization: Bearer <your-token>

Claude Desktop

  1. Open claude_desktop_config.json (macOS default path: ~/Library/Application Support/Claude/claude_desktop_config.json).
  2. Add/update:
{
  "mcpServers": {
    "marsnme-local": {
      "url": "http://127.0.0.1:18790/mcp"
    }
  }
}
  1. Restart Claude Desktop.

Cursor

  1. Open Cursor Settings and search for MCP.
  2. Add a new server:
    • Name: marsnme-local
    • URL: http://127.0.0.1:18790/mcp
    • Headers: optional bearer header if enabled
  3. Reconnect MCP in Cursor.

Warp

  1. Open Settings > Agents > MCP servers.
  2. Add a server pointing to:
    • URL: http://127.0.0.1:18790/mcp
  3. Add optional bearer header if required, then reconnect.

Any MCP client (generic HTTP/SSE)

Use a streamable HTTP/SSE MCP entry:

{
  "marsnme-local": {
    "url": "http://127.0.0.1:18790/mcp"
  }
}

First Connection Validation (Round Trip)

After client connection, verify this sequence once:

  1. tools/list:
curl -sS http://127.0.0.1:18790/mcp \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'
  1. insert_memory:
curl -sS http://127.0.0.1:18790/mcp \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"insert_memory","arguments":{"body":"quickstart memory check","source":"warp","session_id":"quickstart-smoke"}}}'
  1. recall:
curl -sS http://127.0.0.1:18790/mcp \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":3,"method":"tools/call","params":{"name":"recall","arguments":{"query":"quickstart memory check","limit":3}}}'

What this repository is

mars-memory-mcp is the core MCP gateway repository behind the public-facing MarsNMe release.
One codebase (soul-memory/server.mjs) serves multiple profile schemas through MCP_PROFILE. This public repository currently keeps two built-in legacy profile IDs (coco, toto) for backward compatibility.

Current capabilities

  • MCP methods: initialize, notifications/initialized, tools/list, tools/call, ping
  • Profiles: configurable profile IDs (legacy built-ins: coco, toto)
  • Memory tools:
    • insert_memory (short-term memory)
    • list_memories
    • search_memories (Jina embedding search)
    • recall (long-term chunk recall from profile schema)
    • memory_ingest / dream_ingest (long-term chunk ingestion)
    • session_boot / session_close (daily rhythm lifecycle)
    • health_check (coverage, expiry, conflict diagnostics)
    • reload_source_registry (refresh source whitelist at runtime)
    • demote_memory / soft_forget / explain_memory (memory lifecycle management)
  • OAuth-protected MCP endpoint (configurable by environment variables)

Memory model

  • Short-term memory table: <profile>.memories
  • Long-term memory table: <profile>.marsvault_chunks
  • Recommended usage:
    • Keep daily interaction context in insert_memory
    • Promote durable insights through ingest tools

Systemd deployment

Use soul-memory/deploy/systemd/[email protected] with instances:

Recommended env files:

  • /opt/mars-memory-mcp/shared/.env
  • /opt/mars-memory-mcp/shared/.env.profile-a
  • /opt/mars-memory-mcp/shared/.env.profile-b

Release/deploy scripts

  1. Build artifact:
bash soul-memory/deploy/phase2/build_release_artifact.sh
  1. Apply migrations with an explicit DDL-capable role:
npx supabase db push --db-url "<postgres://supabase_admin:<password>@<host>:5432/postgres>"
  1. Run pre-deploy schema gate (must pass before any service restart):
bash soul-memory/deploy/phase2/pre_deploy_schema_gate.sh \
  --db-url "<postgres://supabase_admin:<password>@<host>:5432/postgres>" \
  --profiles coco,toto \
  --expected-role supabase_admin
  1. Run your platform-specific rollout/restart adapter.
    • This repository ships generic artifact + gate scripts; rollout adapters are environment-specific.
    • If schema gate exits non-zero, stop deployment and do not restart services.
  2. Smoke gate:
bash soul-memory/deploy/phase3/smoke_gate.sh --spawn-local
  1. Automated npm + MCP Registry release (tag-driven):
    • Workflow: .github/workflows/publish-release.yml
    • Trigger: push tag v*
    • Gate: tag version must match soul-memory/package.json version
    • Optional local Fish helper:
mrel patch
mrel minor
mrel major
mrel 0.1.2

The helper updates soul-memory/package.json and server.json, commits, tags, and pushes.

Security and version control

  • Never commit .env, runtime tokens, or oauth-clients.json
  • Keep .env.example committed as the only environment template
  • Prefer bearer/OAuth for public exposure
