Indigo Book MCP

Public repo: open-indiana-law/indigo-book. Hosted unofficial MCP: indigo.openindianalaw.org (/mcp).

A local, read-only MCP of The Indigo Book: A Manual of Legal Citation. Full text of the CC0 second edition is searchable and retrievable by rule.

This is not The Bluebook and is not legal advice.

Source

Current edition in the store: Second Edition (2023 updates, 2nd printing), HTML and PDF from indigobook.github.io. The 2022 second edition and 2016 first edition are ingested as additional editions. Public.Resource.Org dedicated the work to the public domain under CC0 1.0.

Cite as: The Indigo Book: A Manual of Legal Citation (Christopher Sprigman & Jennifer Romig et al. eds., Public.Resource.Org 2d ed. 2021).

Tools

  • indigo_search — full-text search

  • indigo_get_rule — one rule or table (R10.2, T3, A)

  • indigo_get_text — rule plus nested subrules, or the whole book

  • indigo_browse — table of contents

Every response names the edition, CC0, and that this is not legal advice.

Setup

python3 -m pip install -e '.[dev]'
python3 -m indigo_book.ingest
INDIGO_BOOK_DB=data/store/indigo-book.db PYTHONPATH=src python3 -m indigo_book.mcp_server
python3 -m pytest

Default MCP transport is stdio. --http serves streamable HTTP on loopback :8766 (landing /, terms /terms, MCP /mcp).

Hosted prototype

A hosted instance runs at https://indigo.openindianalaw.org (MCP endpoint https://indigo.openindianalaw.org/mcp; landing at the root, terms at /terms). Opening /mcp in a browser shows a JSON 406 error: that is the machine protocol, not a broken site. Add it to Claude as a custom connector with that URL, or to Claude Code with claude mcp add --transport http indigo-book https://indigo.openindianalaw.org/mcp.

Usage counts (optional, off by default)

A host can count how often each tool is used. Set INDIGO_BOOK_USAGE_DB to a file path and the server records, per UTC day and per tool or page, only the number of calls (or page opens) 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 indigo_book.usage /path/to/usage.sqlite. The hosted prototype publishes this policy so users know what is and is not measured.

Limits

No Bluebook text is included. No message to Public.Resource.Org. This copy is unofficial and is not legal advice.

This server cannot be deployed

One endpoint for every MCP toolRayrun runs every MCP server behind one URL and holds the credentials. Each call is decided per client, tool, and argument, then recorded.ray.runAd
