ca-leginfo-mcp

An MCP server for California statutes and legislation, built on the Legislature's official public bulk-data channel (downloads.leginfo.legislature.ca.gov).

Lets an attorney's AI tool:

• Verify statutory text from source — current text, history note, and effective date for any section of the 29 California codes or the Constitution

• Flag pending bills that would amend, repeal, or add a given section

• Retrieve legislative history — from a code section to its enacting and amending bills and their committee/floor analyses, back to 1993

Status

Phase 1 (ingest pipeline) complete: the ingest/ package builds current.db from the pubinfo bulk zips (~40 s for the full 2025–26 session + all current law), with a sanity gate that blocks bad artifacts (python -m ingest build / python -m ingest sanity). Tests run against byte-exact real-data fixtures in tests/fixtures/.

Next per SPEC.md: the archive builder (Phase 2), MCP server (Phase 3), deployment (Phase 4). The feasibility spike that preceded the build is preserved in spike/ — see SPIKE_FINDINGS.md.

Data source

All data derives from the California Legislature's public "pubinfo" bulk downloads — the sanctioned distribution channel for this data (the capublic schema published at downloads.leginfo.legislature.ca.gov). No scraping is involved.

This is an unofficial convenience mirror. Statute text refreshes weekly (bills daily); every response carries its extract dates. For court filings, verify against the official publication.

This tool retrieves law; it does not give legal advice.
