UTCP GraphQL Communication Protocol Plugin

This plugin integrates GraphQL as a UTCP 1.0 communication protocol and call template. It supports discovery via schema introspection, authenticated calls, and header handling.

Getting Started

Installation

pip install gql

Registration

import utcp_gql
utcp_gql.register()

How To Use

• Ensure the plugin is imported and registered: import utcp_gql; utcp_gql.register().
• Add a manual in your client config:

  {
    "name": "my_graph",
    "call_template_type": "graphql",
    "url": "https://your.graphql/endpoint",
    "operation_type": "query",
    "headers": { "x-client": "utcp" },
    "header_fields": ["x-session-id"]
  }
  

• Call a tool:

  await client.call_tool("my_graph.someQuery", {"id": "123", "x-session-id": "abc"})
  

Notes

• Tool names are prefixed by the manual name (e.g., my_graph.someQuery).
• Headers merge static headers plus whitelisted dynamic fields from header_fields.
• Supported auth: API key, Basic auth, OAuth2 (client-credentials).
• Security: only https:// or http://localhost/http://127.0.0.1 endpoints.
