Toolcast FAQs

Question 1

What is Toolcast and what problem does it solve?

Accepted Answer

Toolcast is a command-line interface (CLI) tool that transforms any OpenAPI-specified API into an AI agent tool and Model Context Protocol (MCP) server with a single command. It eliminates the manual effort of finding or building custom API integrations for AI agents, streamlining development.

Question 2

How does Toolcast convert an API into an AI agent tool?

Accepted Answer

Toolcast parses any OpenAPI 3.0/3.1 specification (JSON or YAML, from URL or file). It then automatically generates human-readable tool definitions, parameter schemas, and handles authentication, serving them as an MCP server ready for AI agents like Claude Code to interact with.

Question 3

Which AI agent platforms are compatible with Toolcast?

Accepted Answer

Toolcast generates Model Context Protocol (MCP) servers, making it compatible with any MCP client. This includes prominent AI agent platforms like Claude Code and Cursor, allowing your AI agent to seamlessly call real-world APIs.

Question 4

What kind of APIs can I integrate using Toolcast?

Accepted Answer

Toolcast can integrate with any API that provides a valid OpenAPI 3.0 or 3.1 specification. It also comes with a registry of pre-built configurations for popular APIs such as GitHub, Stripe, Slack, Notion, Linear, and OpenAI for quick setup.

Question 5

Does Toolcast support API authentication?

Accepted Answer

Yes, Toolcast automatically detects and supports various authentication methods from your OpenAPI spec, including Bearer Token, API Key, and Basic Authentication. You can provide credentials via environment variables (e.g., `API_TOKEN`, `GITHUB_TOKEN`) or CLI flags like `--bearer-token` or `--api-key`.
