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.

MarsNMe
Why MarsNMe?
Most AI memory tools help AI remember you. MarsNMe helps you and your AI remember each other.
| MarsNMe | Typical memory tool | |
|---|---|---|
| Philosophy | Mutual continuity — human + AI both grow | AI-side context injection only |
| Agent support | Any MCP-compatible client | Often client-specific |
| Memory tiers | Short-term (TTL) + long-term (semantic) | Usually one layer |
| Profiles | Unlimited isolated profiles via MCP_PROFILE | Single-user only |
| Data ownership | Your own Supabase — zero vendor lock-in | Vendor-hosted |
| Search | Jina v3 semantic search (1024-dim pgvector) | Keyword or basic similarity |
| Self-hostable | ✅ Full control | Rarely |
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)
- 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_rolekey →SUPABASE_SERVICE_ROLE_KEY
- Project URL →
- Keep
SUPABASE_SERVICE_ROLE_KEYprivate. Never commit it.
- Create a Jina API key (free tier available):
- Get key: https://jina.ai/api-key/
- Copy key to
JINA_API_KEY
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.
- Clone repository:
git clone https://github.com/Marsmanleo/MarsNMe.git
cd MarsNMe
- Verify Node.js version (20+ required):
node --version
- Copy environment template:
cp .env.example .env
- Fill required values in
.env:SUPABASE_BASE_URLSUPABASE_SERVICE_ROLE_KEYJINA_API_KEY
- 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-urlmust be the Postgres database connection string fromProject 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(notpostgres). - Option B (Supabase Dashboard SQL Editor):
- Open SQL Editor.
- Ensure the
vectorextension is enabled first (Database → Extensions). - Run migration files in filename order from
supabase/migrations/:20260504052744_semantic_vector_dual_profile.sql20260513213800_memory_lifecycle_tracking.sql20260513222500_health_check_detect_conflicts_v2.sql20260517183000_provenance_audit_trail.sql20260517194000_memory_scope_agent_body_environment.sql20260517200500_forget_demote_mechanism.sql20260517223500_usage_cost_telemetry_light.sql20260517231000_memories_source_constraint_regex.sql20260517232000_source_registry_table.sql
- Start gateway:
MCP_PROFILEseparates memory by agent or use case.- Use any profile name you want (for example:
default,my-agent,profile-a). - Legacy built-in profile IDs
cocoandtotoare still supported for compatibility. - If
PORTis omitted, default port is profile-based (coco=18790,toto=18791, other profiles deterministic in20000-29999).
MCP_PROFILE=profile-a PORT=18790 npx @marsnme/mcp-gateway
- Verify health:
curl -sS http://127.0.0.1:18790/health
- 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.
- Set only the required key:
cp .env.example .env
# fill JINA_API_KEY in .env
- 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)
- 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.comURL 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(defaultcoco)MCP_TUNNEL_REQUIRE_BEARER(defaultfalsefor 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
- Open
claude_desktop_config.json(macOS default path:~/Library/Application Support/Claude/claude_desktop_config.json). - Add/update:

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:
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":{}}'
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"}}}'
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:

- OAuth-protected MCP endpoint (configurable by environment variables)
Memory model
- Short-term memory table:
<profile>.memories - Long-term memory table:
