ForgingStack Quorum MCP server

ForgingStack Quorum

Before an agent acts alone, get the quorum. One proposal, N approvals, one receipt.

mcp-name: io.github.jdkabattles/forgingstack-quorum

This is the public client for Quorum. The service itself — the approval flow, the receipt chain, the key store, and billing — runs on ForgingStack's private service and is not in this repo. Copying this repo does not give you the service: you still need an API key and credits, from signup below.

Live API: https://forgingstack-quorum.jkbattles.workers.dev

How it works

1. You propose an action, name the approvers, and set how many approvals are needed (N) and when the proposal expires.
2. Each approver gets a one-time emailed link. Approvals are free.
3. At quorum the proposal is approved and a hash-chained receipt is issued. If it expires first, it expires — no receipt, and the proposal cannot be approved afterwards.
4. You can also reject a pending proposal yourself.

What it does not do: decide if an action is wise, legal, or safe. Quorum only — the approvers decide the rest.

Signup

curl -X POST https://forgingstack-quorum.jkbattles.workers.dev/v1/signup \
  -H "Content-Type: application/json" \
  -d '{"email":"you@example.com"}'

Returns an API key once and 100 starter credits. Save the key immediately — it is stored only as a hash and cannot be shown again. Click the verification link in the signup email before the key can create proposals (if the mail does not arrive, check spam, or POST /v1/verify/resend).

Create a proposal

curl -X POST https://forgingstack-quorum.jkbattles.workers.dev/v1/proposals \
  -H "X-API-Key: YOUR_PRIMARY_KEY" -H "Content-Type: application/json" \
  -d '{"action":"deploy the new build","approvers":["a@example.com","b@example.com"],"required_approvals":2,"expires_at":"2027-01-01T00:00:00Z"}'

Returns the proposal (201) with its approval state and which approval emails were sent. Read it back with GET /v1/proposals/{id}, list yours with GET /v1/proposals, reject a pending one with POST /v1/proposals/{id}/reject. Approvers approve by clicking the link in their email — each link works once. The receipt, once issued, is at GET /v1/receipts/{id}.

Use it (MCP, stdio)

Set the key, then run the MCP server in this repo:

export FORGINGSTACK_API_KEY="your-key-here"
python -m app.mcp_server

Tools: create_proposal, get_proposal, get_credits, get_receipt. See SKILL.md for when to use it and when not to.

Price

1 credit per proposal. Approvals are free. 100 starter credits on signup. $10 for 1,000 credits via POST /v1/billing/checkout (Payment Link). Credits land after payment is verified — usually within the hour.
