Question 1

What is mcp4gql?

Accepted Answer

mcp4gql is a Node.js/TypeScript server that implements the Model Context Protocol (MCP) and acts as a bridge between MCP clients (like Cursor and Claude) and GraphQL APIs.

Question 2

What is MCP (Model Context Protocol)?

Accepted Answer

MCP is an open protocol that standardizes how applications provide context to Large Language Models (LLMs), enabling AI models to access and interact with external data sources and tools.

Question 3

What are the key features of mcp4gql?

Accepted Answer

Key features include MCP Server implementation, Stdio transport, a GraphQL client using `axios`, and tools for GraphQL schema introspection and query execution.

Question 4

What environment variables does mcp4gql require?

Accepted Answer

mcp4gql requires `GRAPHQL_ENDPOINT` (the URL of the GraphQL API) and optionally `AUTH_TOKEN` (a bearer token for authentication).

Question 5

How do I configure Cursor to use mcp4gql?

Accepted Answer

In Cursor settings, add a new global MCP server with the command `npx`, args `-y mcp4gql`, and set the environment variables `GRAPHQL_ENDPOINT` and `AUTH_TOKEN`.

Question 6

How do I configure Claude Desktop to use mcp4gql?

Accepted Answer

In Claude Desktop settings, edit the config and add an `mcpServers` entry for `mcp4gql` with the command `npx`, args `-y mcp4gql`, and set the environment variables `GRAPHQL_ENDPOINT` and `AUTH_TOKEN`.

Question 7

What tools does mcp4gql expose to MCP clients?

Accepted Answer

mcp4gql exposes `introspectGraphQLSchema` (for fetching the GraphQL API schema) and `executeGraphQLOperation` (for executing arbitrary GraphQL queries and mutations).

Question 8

What is UBOS, and how does it relate to mcp4gql?

Accepted Answer

UBOS is a full-stack AI Agent Development Platform that helps orchestrate AI Agents, connect them with enterprise data, build custom AI Agents, and design Multi-Agent Systems. mcp4gql can be integrated with UBOS to provide GraphQL API access within UBOS-orchestrated AI Agent workflows.

Question 9

Can I use mcp4gql without UBOS?

Accepted Answer

Yes, mcp4gql can be used independently to connect MCP clients to GraphQL APIs.

Question 10

What are some use cases for mcp4gql?
