ToolSchema Forge

Builds a complete Model Context Protocol (MCP) server manifest from an OpenAPI 3.x/Swagger 2.0 JSON spec or from a list of LLM tool definitions: MCP tools with input schemas, titles and behavior annotations, server info, capabilities block, HTTP bindings for each operation, and ready-to-run TypeScript stdio server code using the official MCP SDK. Deterministic, no LLM.

Call it from code

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

import { x402Client, wrapFetchWithPayment } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

const client = new x402Client();
registerExactEvmScheme(client, { signer: agentAccount });

const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://toolschema-forge.toolschemaforge.workers.dev/v1/mcp/manifest", { method: "POST" });
console.log(await res.json());
