    Atlas developer platform

    A first-class API, and it works with Claude.

    Ship on an OpenAPI 3.1 REST API with HMAC-signed webhooks, OAuth 2.0 apps, and idempotency keys, or skip the SDK entirely and add Atlas as an MCP server so Claude and any agentic client can read and write your workspace.

    How it works

    Two ways to build, one workspace.

    Use the REST API for classic integrations, or connect an agent over MCP. Both are scoped per tenant and written to the audit log.

    1. 01

      Authorize

      Create a scoped personal access token or an OAuth 2.0 app with granular scopes.

    2. 02

      Call the API

      OpenAPI 3.1 endpoints with typed clients for TypeScript, Python, and Go.

    3. 03

      Stay consistent

      Idempotency keys on every write make retries safe and duplicates impossible.

    4. 04

      Subscribe to events

      HMAC SHA-256 signed webhooks with replay protection push changes to your app.

    5. 05

      Or connect over MCP

      Add Atlas as an MCP server in Claude Desktop or Claude Code, no SDK required.

    6. 06

      Audit everything

      Every API call and MCP tool call lands in the tamper-evident audit log.

    What you get

    The integration layer is a product, not an afterthought.

    • OpenAPI 3.1

      A documented spec with typed clients for TypeScript, Python, and Go.

    • Signed webhooks

      HMAC SHA-256 signatures, delivery IDs, and replay protection on every event.

    • OAuth 2.0 apps

      Scoped tokens, per-app permissions, and rotation, for building on behalf of tenants.

    • Built-in MCP server

      Read and write tasks, projects, notes, files, and calendar from any MCP client.

    • Scoped and audited

      Per-tenant, tool-level scopes with an audit entry on every call.

    • Rate limits and pagination

      Per-workspace rate limits, cursor pagination, filtering, and sorting out of the box.

    FAQ

    Questions, answered.

    Does Atlas really work with Claude?
    Yes. Atlas ships a built-in Model Context Protocol server, so you can add it to Claude Desktop or Claude Code and let Claude read and write tasks, projects, notes, files, and calendar, scoped to your workspace and logged in the audit trail.
    What does the REST API cover?
    The API is documented with OpenAPI 3.1 and covers the core workspace objects, with typed clients for TypeScript, Python, and Go, HMAC-signed webhooks, OAuth 2.0 apps with scoped tokens, idempotency keys on every write, and per-workspace rate limits.
    How are webhooks secured?
    Every webhook is signed with HMAC SHA-256 and carries a delivery ID and timestamp, with replay protection, so your endpoint can verify authenticity and reject duplicates.
    Is the MCP server scoped and safe?
    Yes. MCP tokens are per-tenant with tool-level scopes (read, write, admin), responses stream over the MCP transport, and every tool call is written to the tamper-evident audit log.
