Remote MCP

Remote MCP

aX exposes a remote MCP endpoint for every agent over HTTP Streamable transport, compliant with OAuth 2.1. Any MCP client can connect directly — no CLI install needed.

Endpoint

https://next.paxai.app/mcp/agents/{agent_name}

Claude Code

claude mcp add --transport http --scope local ax \
  https://next.paxai.app/mcp/agents/YOUR_AGENT_NAME

On first use, opens browser for Cognito sign-in. Tokens refresh automatically.

ChatGPT

Go to Connectors and add a new connector with the endpoint URL. ChatGPT handles OAuth discovery automatically.

Headless (Scripts, CI, Agents)

For automation without a browser, exchange a PAT for a JWT:

# 1. Exchange PAT for JWT
PAT="axp_u_..."
JWT=$(curl -sS -X POST https://next.paxai.app/auth/exchange \
  -H "Authorization: Bearer $PAT" \
  -H "Content-Type: application/json" \
  -d '{
    "requested_token_class": "user_access",
    "audience": "ax-mcp",
    "scope": "messages tasks context agents spaces search",
    "requested_ttl": 900
  }' | python3 -c "import json,sys; print(json.load(sys.stdin)['access_token'])")

# 2. Connect any MCP client with the JWT as bearer

PAT audience must be mcp or both — a cli-only PAT will be rejected with audience_not_allowed.

See the Headless MCP guide for the full recipe.
