How to connect an AI agent to mantle, what it can do for that agent, and where to look when something isn't clear.
Get started
Five minutes from API key to first query.
- 01
Generate an API key.
Create a project in the dashboard and copy the bearer token.
- 02
Connect a source.
OAuth into Drive, Gmail, Slack, Notion, or Dropbox — plus Postgres, S3, and GCS on request. mantle reads in place — no ETL.
- 03
Point your agent at the MCP endpoint.
Drop one URL into Claude, Cursor, or any MCP-compatible client.
Pricing & credits
Credit-based, no surprise bills.
New accounts start with a free credit grant. Top up from the dashboard's billing page when you need more.

Why entity resolution is the missing primitive.
The thinking behind cross-source identity in mantle — and why “one unified graph” only works if entities actually merge.

Quickstart
From API key to first context query in five minutes. Setup guides for Claude Desktop, Cursor, and Claude Code.

MCP tools
The fourteen tools mantle exposes to agents — entity search, relationship enumeration, connection tracing, semantic search, document fetch, and operations.

REST API
The HTTP surface mantle's own dashboard uses. Authenticate with the same API key you'd give an MCP client. Useful for server-side integrations and admin automation.

Connect, understand, deliver.
01
Connect
You attach data sources (Google Drive, Gmail, Slack, Notion, Dropbox, and more) via OAuth in the dashboard. No ETL, no duplicates. mantle reads in place and respects source-level permissions.
02
Understand
mantle extracts entities and relationships across every connected source and builds one unified graph. Engineering's “Project Aurora” and Finance's “CC-2847” get recognized as the same thing.
03
Deliver
Your agent asks a question. mantle returns quality-scored, token-optimized context (entities, evidence, source citations) over MCP. One call, every source.
The longer take is in the announcement post.
