Quickstart

Name: Mantle
Author: mantle

Five minutes from API key to your agent answering questions about your data. Pick the client you use — the rest is paste-and-go.

Step 0

Get an API key.

mantle is currently in pre-release. Once access opens, sign in at app.mantleai.dev, create a project, and copy the mk_… bearer token. The same key will work across REST and MCP.

You'll then be able to connect at least one source — Drive, Gmail, Slack, or Dropbox — so you have something to query.

Client

Claude Desktop

Claude Desktop talks MCP over stdio, so we use mcp-remoteto bridge to Mantle's HTTP MCP endpoint. Open Claude Desktop → Settings → Developer → Edit Config and paste:

{
  "mcpServers": {
    "mantle": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.mantleai.dev/mcp",
        "--header",
        "Authorization:Bearer mk_your_key_here"
      ]
    }
  }
}

Save, restart Claude Desktop. The Mantle tool catalog appears in the tool picker. Ask “What did Maren and the Acme team last discuss?” — Claude will resolve the entity and pull from every connected source.

Client

Cursor

Cursor speaks HTTP MCP natively — no bridge needed. Open ~/.cursor/mcp.json and add:

{
  "mcpServers": {
    "mantle": {
      "url": "https://mcp.mantleai.dev/mcp",
      "headers": {
        "Authorization": "Bearer mk_your_key_here"
      }
    }
  }
}

Reload Cursor. The Mantle tools appear in the agent panel.

Client

Claude Code

A single CLI command registers Mantle as an HTTP MCP server:

claude mcp add mantle \
  --transport http \
  --url https://mcp.mantleai.dev/mcp \
  --header "Authorization:Bearer mk_your_key_here"

Run claude mcp listto confirm. Mantle's tools are now available in any Claude Code session.

Anything else

Custom agents.

Any MCP-compatible agent can connect to Mantle. Point it at https://mcp.mantleai.dev/mcp with your API key as a bearer token. For server-side integrations that don't need MCP, use the REST API directly — see the API reference.
