What does it do vs a router?
It is a cost meter, not a router. It tells you what you spent and which provider fits a workload, but never changes your calls. It pairs happily alongside a router or a model-leaderboard tool.

A local-first, multi-provider cost meter for LLM usage, exposed as MCP tools. Captures every call into a local SQLite ledger and lets any coding agent query spend, compare providers, and get recommendations — no cloud, no account. First-class support for Chinese providers (Qwen,

Llm Usage & Cost Tracker is a local-first MCP server and CLI that captures LLM API calls across multiple providers (Anthropic, OpenAI, DeepSeek, Qwen), calculates costs, and answers spend queries through an agent or terminal. It is a cost meter, not a router.
Install via uv tool install llm-usage-mcp (or clone from source). Set at least one provider API key as an environment variable. Run the capture proxy (llm-usage-proxy), which listens on 127.0.0.1:5525. Point your LLM client’s base URL to the proxy. Use the MCP server (e.g., claude mcp add llm-usage -- uv run llm-usage-mcp) to ask agent questions, or run CLI commands like llm-usage spend, llm-usage compare, and llm-usage recommend.

Python 3.13+, uv or pipx for installation. SQLite is built into Python, no extra database setup.
All data is stored locally in a SQLite file at `~/.llm-usage/usage.db`.
Anthropic, OpenAI, DeepSeek, and Qwen are supported for both streaming and non-streaming. More providers (Gemini, Bedrock, Moonshot) are planned.
API keys are set as environment variables (e.g., `ANTHROPIC_API_KEY`). The proxy holds keys server-side; clients point their base URL at `http://127.0.0.1:5525` and never need keys directly.
