Original: Agentic Ledger: an open source flight recorder for AI agents (looking for testers and contributors)

Short summary

Agentic Ledger is an open-source transparent proxy that sits between AI agents and LLM providers, recording every request and response with real cost accounting — no SDK or code changes required. It infers agent loops from raw traffic, flags cost-wasting pathologies, enforces hard USD budgets, and includes an MCP server for agents to query their own usage. The tool supports Claude Code, Cursor, LangGraph, CrewAI, AutoGen, and many other frameworks out of the box.

  • Transparent proxy records all LLM calls with per-call cost accounting, no SDK needed
  • Loop awareness detects cost-wasting agent patterns and can act as circuit breaker
  • Supports Claude Code, Cursor, LangGraph, CrewAI, and 15+ other frameworks
  • MIT licensed, local-first with SQLite or Postgres backend

Generated with AI, which can make mistakes.

Is this a good recommendation for you?
