The Federal Register publishes hundreds of regulatory changes every day. For estate attorneys, that firehose is mostly noise — a Treasury technical correction on valuation discounts matters; a routine notice of meeting does not. And for AI agents trying to answer "what changed in federal estate tax law this week," there's no clean API. You're stuck scraping PDFs, parsing dense legal prose, or paying for walled-garden legal research platforms that cost more than they're worth for a single question.
I built ForgePoint Signal to fix that. It monitors federal estate, gift, trust, and inheritance tax changes, parses them into structured summaries, and exposes everything over MCP so agents can query it directly. Some tools are free, the rest cost 10¢ per call in USDC — no signup.
What I Built
Ingest — A GitHub Actions cron runs daily. It pulls estate-tax and gift-tax documents from the Federal Register API and the IRS Internal Revenue Bulletin, then dedupes on document number.
Parse — Claude extracts a plain-English summary, impact level (low/medium/high), and effective date for each document.
Store — Results go into Supabase, keyed uniquely on source URL so the cron is idempotent.
Serve — A Vercel serverless function hosts the MCP server. Paid tools are gated with x402 — $0.10 USDC on Base mainnet.
The MCP Server
Four tools. One free, three paid. Here's the one agents use most:
{
"name": "search_regulations",
"description": "Search the full ForgePoint Signal regulatory database by keyword, jurisdiction, category, or impact level. Returns full entries with plain-English summaries and source links. Updated daily."
}
How x402 Works
Agent calls a paid tool. No payment attached.
Server returns 402 with payment requirements — $0.10 USDC on Base, 120 second window.
x402 client signs a USDC transfer and retries with an X-PAYMENT header.
Server verifies via x402 facilitator, executes the tool, returns data with a receipt header.
No API keys. No accounts. No Stripe webhooks. The payment is the auth.
How to Connect It
{"mcpServers":{"forgepoint-signal":{"url":"https://forgepointsignal.com/mcp"}}}
Drop that into any MCP client — Claude Desktop, Cursor, Cline. preview_regulations is free. Everything else is metered at $0.10 USDC.
What's Next
A human dashboard with full-text search and email alerts. A $199/month Stripe tier for users who don't want to think in micropayments. More data sources — IRS Internal Revenue Bulletin, state revenue departments, Tax Court opinions.

The explorer above is connecting to forgepointsignal.com/mcp and probing its tools via the Anthropic API. Here's what it does:
Discovers all available tools — names, descriptions, and parameters
Expandable cards — click any tool to see its parameters (required vs optional)
"Try this tool" button — sends a prompt to test any tool directly
If the connection succeeds, you'll see the full tool list. If it returns a raw response (the server may use a non-standard format), it'll show the raw JSON so we can parse it manually. Let me know what comes back and we can dig deeper!
Thanks for taking a look. Quick clarification — when you say "the explorer above," what tool are you running? There's no explorer embedded in the post itself, so I'm wondering if you connected via Claude Desktop, a custom MCP client, or something like Smithery's inspector. Also curious what tools you saw on the list — there should be four specific ones.
