### Description (declared)

# mcp-surfaceprint
[![Downloads](https://static.pepy.tech/badge/mcp-surfaceprint)](https://pepy.tech/project/mcp-surfaceprint)
[![PyPI version](https://img.shields.io/pypi/v/mcp-surfaceprint.svg)](https://pypi.org/project/mcp-surfaceprint/)

Inspect, fingerprint, and diff an MCP server’s declared capability surface.

An MCP server can gain tools, parameters, resources, prompts, or new actions beneath an existing tool name. `mcp-surfaceprint` captures that client-visible surface as a deterministic snapshot, computes a stable digest when inspection is complete, and shows structural differences over time.

Use it as:

- an interface compatibility check for MCP server maintainers
- a capability-change review gate for teams consuming third-party MCP servers

If you want the deeper framing and experiments, see [You can’t prove an MCP server hasn’t changed](You%20can%E2%80%99t%20prove%20an%20MCP%20server%20hasn%E2%80%99t%20changed.md).

## Why

You review an MCP server before installing it. Later, a dependency upgrade adds a destructive action beneath an existing tool name. The package version changed, but nothing gives you a durable, structural record of the declared capability surface you previously reviewed.

`mcp-surfaceprint` turns that declaration into a versioned artifact that can be committed, compared, and reviewed.

## Quick start (snapshot + check)

```bash
pipx install mcp-surfaceprint

# Commit a baseline snapshot (one-time)
mcp-surfaceprint --save mcp-surface.json "uv run server.py"
git add mcp-surface.json

# Later, locally or in CI: check the live server against the baseline
mcp-surfaceprint check mcp-surface.json "uv run server.py"
```

A changed surface is not automatically unsafe; `check` turns it into an explicit review event rather than allowing it to pass unnoticed.

> **Safety:** This command starts the server locally. MCP discovery does not invoke its declared tools, but a server can execute arbitrary code while handling any request. Use `--isolate…
