## プロジェクトの歴史と使われ方

mcpsnoop is a transparent proxy and terminal interface for observing Model Context Protocol traffic between an actual AI client and its MCP servers. It captures JSON-RPC frames from stdio or streamable-HTTP connections and supports live inspection, replay, export, comparison, and automated checks.

### プロジェクトの歴史

The project appeared publicly in June 2026 with an initial v0.1.0 release. It was designed to complement MCP Inspector by sitting directly in the client's real data path rather than establishing a separate inspection connection.

### 採用の歴史

The project distributes a single Go binary through GitHub releases, `go install`, and Homebrew. Its early release series moved from v0.1.0 in June 2026 to v0.16.0 in July 2026, adding workflows for saved sessions and CI-oriented protocol checks alongside the interactive TUI.

### 使われ方

For stdio servers, users replace the configured server command with `mcpsnoop -- <server command>` and run `mcpsnoop` separately to open the TUI. For streamable HTTP, `mcpsnoop http` acts as a reverse proxy. Commands can reopen, export, compare, replay, validate, and prune captured sessions.

### パッケージ好きにとっての重要性

mcpsnoop brings packet-inspection conventions to MCP without requiring a language-specific SDK or modified server. Its single-binary packaging and CI exit codes make captured agent-tool traffic usable both interactively and as a reproducible test artifact.

### タイムライン

- 2026: The official repository and v0.1.0 release appeared on June 27.
- 2026: Version v0.16.0 was released on July 27.

### Related projects

- MCP Inspector is the official comparison point; mcpsnoop differs by observing the user's real client-server connection.
- Model Context Protocol and JSON-RPC define the traffic mcpsnoop captures and validates.
