AI Tooling

@delilah/mcp is a Model Context Protocol server that puts the Delilah API inside Claude and any other MCP-compatible assistant. Ask a question in plain language; the assistant calls the same endpoints you would.

Install

The server runs locally over stdio and needs no install step — npx fetches it on demand. All it needs is your API key in DELILAH_API_KEY.

bash

DELILAH_API_KEY=dk_live_… npx @delilah/mcp

Claude Desktop

Add the server to claude_desktop_config.json, then restart Claude Desktop. On macOS the file lives at ~/Library/Application Support/Claude/claude_desktop_config.json; on Windows, at %APPDATA%\Claude\claude_desktop_config.json.

json

{
  "mcpServers": {
    "delilah": {
      "command": "npx",
      "args": ["-y", "@delilah/mcp"],
      "env": {
        "DELILAH_API_KEY": "dk_live_…"
      }
    }
  }
}

Other MCP clients — Claude Code, editors, and custom agents — take the same command, args, and environment.

Tools

Tool	What it does
`search_bills`	Search bills by state, session, bill number, sponsor, status, subject, or free text
`get_bill`	One bill, with an `include` for votes, sponsors, history, and texts
`get_legislator`	A member's profile, voting record, and sponsored bills
`list_committees`	Committees by state and chamber
`semantic_search_bills`	Natural-language bill search when you do not know the bill number
`get_coverage`	Per-state depth and freshness, so the assistant can qualify its own answers

What it will not do

Read-only. Every tool maps to a GET. The server never writes, never creates webhooks, and never spends anything.
No hidden failures. API errors are surfaced verbatim — code, message, and request_id — rather than summarized away, so you can tell a missing record from an expired key.
Your limits apply. Calls count against the same burst limit and monthly cap as direct requests; see Rate limits.

Try it

Once the server is connected, ask the assistant things like:

“What Florida bills on short-term rentals moved in the last week?”
“How did each senator vote on the third reading of HB 1?”
“Which committees has this member sat on, and what did they sponsor?”

Keys are issued after a short review — no self-serve signup. Request API access and tell us what you are building.
