devmind-mcp-server

MCP server for DevMind — persistent memory for AI coding assistants (Claude Code, Cursor) backed by Walrus + MemWal + Seal on Sui.

Once installed, Claude Code / Cursor / any MCP-compatible client can:

• save_memory — push a decision, bug, arch note, or general note into your team's shared memory queue (awaits human approval, then encrypted + uploaded to Walrus via MemWal).
• get_memory — semantic search across your team's approved memories.
• share_context — push context directly to another workspace member.
• save_artifact — store a file (dataset, log, report) to Walrus.

Memories survive across sessions, tools, and team members. The PR Reviewer Agent reads them autonomously to flag PRs that violate past decisions.

Install

npm install -g devmind-mcp-server

That installs the devmind-mcp binary globally.

Setup

You need:

1. A DevMind workspace (create one at https://devmind.app or your self-hosted dashboard)
2. An API token (dm_sk_*) from the /connect page

Claude Code

Add to ~/.claude.json:

{
  "mcpServers": {
    "devmind": {
      "command": "devmind-mcp",
      "env": {
        "DEVMIND_API_BASE_URL": "https://api.devmind.app",
        "DEVMIND_API_TOKEN": "dm_sk_xxxxx",
        "DEVMIND_WORKSPACE_ID": "cmpxxxxxxxxxx"
      }
    }
  }
}

Restart Claude Code. Verify with /mcp — you should see devmind connected.

Cursor

Add to .cursor/mcp.json in your project root (same shape as above).

Custom MCP client

const client = new McpClient({ transport: "stdio" })
await client.connect({
  command: "devmind-mcp",
  env: {
    DEVMIND_API_BASE_URL: "https://api.devmind.app",
    DEVMIND_API_TOKEN: "dm_sk_xxxxx",
    DEVMIND_WORKSPACE_ID: "cmpxxxxxxxxxx",
  },
})

Environment Variables

| Var | Required | Description | |---|---|---| | DEVMIND_API_BASE_URL | yes | DevMind backend URL (e.g. https://api.devmind.app) | | DEVMIND_API_TOKEN | yes | API token dm_sk_* — generate at /connect page | | DEVMIND_WORKSPACE_ID | yes | Workspace ID this MCP client should save/recall against |

Self-hosting the backend

The MCP server only speaks to a DevMind backend. If you self-host the backend (Fastify + Postgres + Walrus testnet), point DEVMIND_API_BASE_URL at your instance.

See https://github.com/DevMindRepo/MonoRepo for the full stack (backend, frontend, smart contracts, PR Reviewer Agent).
