Graft FAQs

Question 1

What is Graft and what problem does it solve?

Accepted Answer

Graft is a software tool that unifies API exposure, allowing developers to define API 'tools' once and expose them as both traditional HTTP endpoints and Model Context Protocol (MCP) tools for AI agents. This eliminates the need to split server models and ensures a consistent pipeline for authentication, validation, and middleware across all access methods.

Question 2

How does Graft specifically benefit AI agent development?

Accepted Answer

Graft is designed to be 'agent-ready'. It exposes your defined tools as MCP endpoints, providing AI agents with structured access to your API's capabilities. It also generates agent discovery documents, exposes read-only resources, and allows for reusable prompt templates, making it easier for AI agents to discover, understand, and interact with your services.

Question 3

Can I use Graft with an existing API or does it require a new project?

Accepted Answer

Graft can be integrated into new projects or used to wrap existing APIs. You can wrap an existing API by providing its OpenAPI specification or defining specific endpoints via a YAML configuration. This allows you to expose existing functionalities to AI agents and HTTP clients without requiring any code changes to your original API.

Question 4

What kind of documentation and discovery features does Graft provide?

Accepted Answer

Graft automatically generates a comprehensive suite of documentation and discovery assets. This includes OpenAPI 3.1 specifications, interactive API reference documentation (powered by Scalar), agent discovery files (`.well-known/agent.json`), MCP server cards (`.well-known/mcp.json`), and concise tool listings for LLMs.

Question 5

What programming languages or frameworks does Graft support?

Accepted Answer

Graft is primarily built with TypeScript and offers native integration for TypeScript-based applications, including support for Bun, Deno, and Cloudflare Workers. However, its ability to wrap existing APIs via OpenAPI or YAML configurations means it can expose tools from any language or framework to agents and HTTP clients.
