# MCP Servers (official)

> Reference Model Context Protocol servers: memory, git, filesystem and more, ready to plug into any MCP client.

**What:** Standard plug-in tools for agents. **Why:** Gives a local agent hands: files, git and more.

**Stack layer:** tools (model → runtime → harness → memory → tools)

The official collection of reference MCP server implementations. TypeScript servers run via npx, Python servers via uvx or pip.

**Gap role:** Tool use: gives local agents the same standardized tools (files, git, memory, fetch) frontier assistants use.

## Gap Score

null (pending test on Mac Studio)

## Prerequisites

- Node.js (for npx servers)
- uv/uvx (brew install uv) for Python servers
- An MCP-capable client

## Install

### macOS (Apple Silicon)

1. Run:

```bash
brew install node uv
```

2. runs the Memory server (stdio):

```bash
npx -y @modelcontextprotocol/server-memory
```

3. runs the Git server; or: pip install mcp-server-git && python -m mcp_server_git:

```bash
uvx mcp-server-git
```

## Configure

1. the README's client example uses Claude Desktop; other clients use the same command/args shape:

```bash
# add to your MCP client's config, e.g.
{
  "mcpServers": {
    "memory": {"command": "npx", "args": ["-y", "@modelcontextprotocol/server-memory"]}
  }
}
```

## Verify

1. Expect: MCP Inspector opens in your browser and lists the server's tools

```bash
npx @modelcontextprotocol/inspector npx -y @modelcontextprotocol/server-memory
```

## Rollback

1. Run:

```bash
# remove the server entry from your MCP client config and restart the client
```

2. Run:

```bash
npm cache clean --force   # optional, clears npx downloads
```

## One-command install

Status: docs-checked (Not run: commands checked against the official docs only). The wrapper scripts are generated from the site data. Every .sh passed bash -n and shellcheck and ran in plan mode on Linux (Debian 13). Every .ps1 passed the PowerShell parser and chat.ps1 ran in plan, verify and rollback mode under PowerShell 7 on Linux with Windows calls mocked. Not run on macOS or real Windows.

```bash
curl -fsSL https://insidethemachine.ai/install/mcp-servers.sh | bash            # install, then check
curl -fsSL https://insidethemachine.ai/install/mcp-servers.sh | bash -s -- plan    # print only
curl -fsSL https://insidethemachine.ai/install/mcp-servers.sh | bash -s -- rollback --yes
```

Details and Windows: https://insidethemachine.ai/install/mcp-servers.md

## Caveats

- Reference servers are examples, not hardened production services; review each server's README.

## Benchmarks

Status: pending test on Mac Studio. Rig: Mac Studio, Apple Silicon, 128GB unified memory. No results published yet.
