MCP To Typescript Codegen

mcp到打字代码生成器

从MCP（模型上下文协议）服务器生成TypeScript类型。

安装

npm install -g mcp-to-typescript-codegen

或者与npx一起使用：

npx mcp-to-typescript-codegen --command "your-mcp-server"

用法

标准传输（本地服务器）

# Basic usage
mcp-to-typescript-codegen --command "mcp-server"

# With arguments
mcp-to-typescript-codegen --command "npx" --args "@modelcontextprotocol/server-filesystem,/tmp"

# Custom output file
mcp-to-typescript-codegen --command "mcp-server" --output "./types/mcp.ts"

# With namespace prefix (for multiple servers)
mcp-to-typescript-codegen --command "apollo-mcp" --name Apollo --output "./types/apollo.ts"

HTTP传输（远程服务器）

mcp-to-typescript-codegen --server "http://localhost:3000/mcp"

选项

生成的输出

// Auto-generated by mcp-to-typescript-codegen
// Do not edit manually

export type ReadFileParams = {
  path: string;
};

export type ListDirectoryParams = {
  path: string;
};

export type ToolName = "read_file" | "list_directory";

export const toolNames = ["read_file", "list_directory"] as const;

随着 --name Apollo:

export type ApolloExecuteParams = {
  query: string;
  variables?: string;
};

export type ApolloToolName = "execute" | "introspect";

export const apolloToolNames = ["execute", "introspect"] as const;

使用生成的类型

import { ReadFileParams, ToolName } from "./generated/mcp-tools";

// Type-safe params
const params: ReadFileParams = {
  path: "/etc/hosts",
};

// Type-safe tool name
const toolName: ToolName = "read_file";

多个MCP服务器

为具有不同前缀的多个服务器生成类型：

# Apollo GraphQL MCP
mcp-to-typescript-codegen -c "apollo-mcp" -n Apollo -o "./types/apollo.ts"

# Filesystem MCP
mcp-to-typescript-codegen -c "npx" -a "@modelcontextprotocol/server-filesystem,/tmp" -n Filesystem -o "./types/filesystem.ts"

然后导入每个：

import { ApolloExecuteParams, ApolloToolName } from "./types/apollo";
import { FilesystemReadFileParams, FilesystemToolName } from "./types/filesystem";
