Indiana Code

Indiana Code MCP

Public home: Open Indiana Law (open-indiana-law/indiana-code). Unofficial MCP: mcp.openindianalaw.org (/mcp). This copy is unofficial and is not legal advice.

Dated, unofficial copies of Indiana legal text as a local MCP server. Structured Indiana Code for 2017–2026; official IGA companions as far back as IGA publishes them; current court-rules PDFs; Indiana appellate clusters with opinion bodies when Harvard CAP or official court PDFs supplied them.

This is an access layer, not an official publication, and not legal advice. Verify every citation at iga.in.gov.

The older IGA-API / opinions server in src/mcp_server.py is historical and is not wired to any database. Use python -m indiana_law.mcp_server.

Setup

python3 -m venv .venv
source .venv/bin/activate
pip install -e ".[dev]"

# Point at a built store (this checkout already has one):
export INDIANA_LAW_DB="$PWD/data/store/indiana-code.db"

Rebuild from the official JSONL already on disk: docs/REBUILD.md. Coverage limits: NOT_COVERED.md.

python -m pytest tests
INDIANA_LAW_DB=data/store/indiana-code.db python scripts/smoke_mcp.py

Run the MCP server (stdio)

export INDIANA_LAW_DB=/absolute/path/to/indiana-code.db
python -m indiana_law.mcp_server

Cursor

Add to ~/.cursor/mcp.json (or the project MCP config):

{
  "mcpServers": {
    "indiana-code": {
      "command": "python",
      "args": ["-m", "indiana_law.mcp_server"],
      "env": {
        "INDIANA_LAW_DB": "/absolute/path/to/indiana-code.db",
        "PYTHONPATH": "/absolute/path/to/indiana-law/src"
      }
    }
  }
}

If you installed the package into a venv, use that venv's python and you can drop PYTHONPATH.

Usage counts (optional, off by default)

A host can count how often each tool is used. Set INDIANA_LAW_USAGE_DB to a file path and the server records, per UTC day and per tool, only the number of calls and errors. It never sees or stores IP addresses, queries, arguments, results or session ids, so the totals cannot identify anyone, and a failure to write a count never breaks a tool. Read the totals with python -m indiana_law.usage /path/to/usage.sqlite.
