MCP quickstart

Connect a remote MCP client to Sume's production endpoint, complete OAuth (or use an API key), then call a read-only discovery tool.

1. Use the production URL

Do not paste API keys into chat. Prefer the OAuth connector flow for interactive clients.

2. Connect Claude Code

Confirm the server is connected in Claude Code's MCP status UI, then ask Claude to call tools.list or mcp.health.

3. Connect Cursor

Add a remote MCP server entry (Cursor Settings → MCP, or your MCP config file):

Complete the OAuth sign-in when Cursor prompts you. After connect, call tools.list once to verify the session.

4. Connect Codex or other HTTP MCP clients

Point a streamable HTTP MCP server at:

Run that client's OAuth login for the configured server name. The client should discover Sume protected-resource metadata from the MCP endpoint and send you to Sume sign-in at app.sume.com.

5. Verify with a read-only tool

Ask the agent:

Useful first calls:

ToolWhy
mcp.healthConfirms endpoint, auth source, and safety posture.
tools.listLists every tool visible to this session.
tools.schemaReturns one tool contract by name.
account.meConfirms workspace account context.
catalog.listLists public API capabilities (broader than MCP tools).

6. Know the Phase-1 OAuth limit

Hosted OAuth Phase 1 grants read-only access (mcp:read).

With OAuth:

  • Read tools such as jobs.list, assets.get, and catalog.list work.
  • Write tools such as jobs.cancel or assets.create are denied.
  • Paid tools such as avatars.create are denied.

To run write or paid MCP tools today, use an API-key remote MCP session or the Developer API / CLI. See OAuth and API keys and Tools and gates.

Local CLI alternative

If the agent can run shell commands on your machine, prefer direct CLI commands today (sume login, sume tools list --json, Avatar submit + sume jobs …). See the CLI overview.

Local sume mcp is not launched in current CLI releases (coming_soon). It is a separate future surface from the hosted connector at mcp.sume.com. Prefer hosted MCP when the client speaks remote HTTP MCP.

Studio Agent is different

Studio Agent is the in-app Sume agent product. It is not the public hosted MCP connector documented on these pages. Do not configure Studio Agent internals as a customer MCP server URL.
