中文说明

MCPSvr is a lightweight web directory for Model Context Protocol servers. It helps developers browse available servers, understand how each one is configured, and contribute new entries through pull requests.

The repository centers on a curated public/servers.json registry, so MCP clients such as 5ire can install and run supported servers directly.

Why MCPSvr

MCP servers are growing fast, but good discovery is still fragmented. MCPSvr gives the ecosystem a simple shared registry with enough metadata for humans to evaluate tools and for clients to automate setup.

What You Can Do

- Discover MCP servers from a single browsable directory
- Review runtime commands, arguments, environment variables, and homepage links
- Contribute new servers or improve existing metadata via pull requests
- Reuse the registry in MCP clients that support direct installation

Run Locally

Prerequisites

- Node.js 18+ - npm (or another package manager compatible with package-lock.json)

Install

npm install

Start the development server

npm run dev

Then open http://localhost:3000.

Build for production

npm run build
npm run start

How to Add a Server

All registered MCP servers are maintained in public/servers.json. To contribute a new entry:

1. Fork the repository
2. Add or update a server object in public/servers.json
3. Keep keys consistently ordered
4. Open a pull request with links to the project homepage or docs

Server Schema

{
  "name": "Server Identifier",
  "key": "Unique alphanumeric identifier",
  "description": "Concise implementation overview",
  "command": "Execution environment specifier (for example uvx, npx, python, node)",
  "args": [
    "Required runtime arguments"
  ],
  "env": {
    "ENVIRONMENT_VARIABLE": "Value assignment"
  },
  "homepage": "Official documentation URL"
}

Field Guidelines

- key must be unique, alphanumeric, and start with a letter - name is optional and falls back to key when omitted - env and homepage are optional but strongly recommended - Keep descriptions short and practical so clients can display them cleanly

Parameter Placeholders

When a server needs user-provided input, use the placeholder format below:

{{paramName@paramType::paramDescription}}

Example:

{
  "name": "File System Access Control",
  "key": "FileSystem",
  "command": "npx",
  "description": "Enforces directory-level operation restrictions through specified arguments",
  "args": [
    "-y",
    "@modelcontextprotocol/server-filesystem",
    "{{dirs@list::directories you are about to access, include trailing slash}}"
  ],
  "homepage": "https://github.com/modelcontextprotocol/servers"
}

Supported placeholder types include string, list, and number.

Contribution Notes

- Prefer accurate metadata over marketing copy
- Double-check command arguments before submitting
- Include a homepage or docs link whenever possible
- If you add a new field in the future, keep the schema backwards compatible for downstream clients
