aspy is an observability proxy marketplace for Claude Code that intercepts Anthropic API traffic so developers can inspect tool calls, thinking, tokens, and costs.
About
aspy is a Claude Code observability marketplace bundling a proxy, MCP server, and plugin to see what happens between Claude Code and the Anthropic API. Reach for it when you need real-time insight into tool calls, thinking blocks, token spend, and structured session logs while debugging agent behavior or recovering prior context. Point Claude Code at the local proxy, optionally add aspy-mcp, and query stats through the plugin or programmatic APIs.
- TUI proxy between Claude Code and the Anthropic API
- JSON Lines logs plus REST API and MCP access
- Per-session and lifetime semantic recall of thinking blocks
- Optional Claude Code plugin with /aspy:stats slash command

FAQ
How do you route Claude Code through Aspy?
README sets ANTHROPIC_BASE_URL to http://127.0.0.1:8080 after starting the local proxy binary.
What programmatic interfaces exist?
README lists REST API, MCP tools such as Aspy_stats and Aspy_recall, and optional plugin slash commands.
Does the MCP server work without the proxy?
README notes the TUI proxy must be running to collect data that MCP recall and stats expose.
