Why ledgermind?

Local LLM cost & token forensics proxy with anomaly detection — without standing up heavyweight infrastructure.

ledgermind is single-purpose, scriptable, and self-hostable: point it at a target, get prioritized results in the format your workflow already speaks (table · JSON · SARIF), gate CI on it, and let agents drive it over MCP.

Quick start

pip install cognis-ledgermind
ledgermind --version
ledgermind scan .                       # scan current project
ledgermind scan . --format json         # machine-readable
ledgermind scan . --fail-on high        # CI gate (non-zero exit)

<a name="example"></a>

Example

$ ledgermind scan .
  [HIGH    ] LED-001  example finding             (./src/app.py)
  [MEDIUM  ] LED-002  another signal              (./config.yaml)

Use it from any AI stack

ledgermind is interoperable with every popular way of using AI:

  • MCP serverledgermind mcp (Claude Desktop, Cursor, Cognis.Studio, uncensored-fleet)
  • OpenAI-compatible / JSON — pipe ledgermind scan . --format json into any agent or LLM
  • LangChain · CrewAI · AutoGen · LlamaIndex — wrap the CLI/JSON as a tool in one line
  • CI / scripts — exit codes + SARIF for non-AI pipelines
