OpenContext — Anchorage Open Checkbook fork

This fork of OpenContext deploys the Anchorage Open Checkbook MCP (anchorage_checkbook plugin) — read-only tools over the Municipality of Anchorage's unaudited expenditure, payroll, procurement, and revenue tables, with the dataset's traps (duplicate double-loads, snapshot dates, net amounts, unnormalized vendor names) encoded in tool behavior. See docs/CHECKBOOK.md and METHODOLOGY.md — this server's totals deliberately differ from the public MOA dashboard (duplicates are filtered by default).

Quick Start

# 1. Configure (this fork ships its config ready to go)
cp config-anchorage-checkbook.yaml config.yaml

# 2. Test locally
pip install aiohttp
python3 scripts/local_server.py

# 3. Deploy
./scripts/deploy.sh --environment staging

Connect via Claude Connectors (same steps on both Claude.ai and Claude Desktop):

1. Go to Settings → Connectors (or Customize → Connectors on claude.ai)

2. Click Add custom connector

3. Enter a name (e.g. "Anchorage Open Checkbook") and your API Gateway URL

Get the URL: cd terraform/aws && terraform output -raw api_gateway_url

See Getting Started for full setup.

Documentation

Try it

The public deployment is at https://checkbook.codeforanchorage.org/mcp. Add it as a custom connector and ask questions like:

• "What did the Municipality of Anchorage spend by department in FY2025?"

• "How much has MOA paid Chugach Electric, across every spelling of the name?"

• "Show me procurement over $1M in FY2024."

Every answer comes back with its qualifications attached — figures are net of offsetting entries, duplicate ETL rows are filtered by default, and known data gaps are flagged rather than reported as zero. See Methodology for why these totals deliberately differ from the public MOA dashboard.
