Cubiczan Agent Platform

Identity, money, and evidence for agents that actually ship.

Three SKUs, one workspace. MCP clients keep a Bearer principal through tools/call and SSE. Spend cannot settle without a mandate and, over cap, a human second key. Board claims cannot seal without an agent, a CHP lock, and a hashed document.

Shared primitives (packages/shared): CHP gate, HMAC ledger, HTTP/SSE helpers. Zero runtime npm dependencies. Stripe and x402 are rails — tests never call live networks.

Quickstart

npm install
npm test
npm run gateway   # :7474
npm run spend     # :7475
npm run cfo       # :7476

Demo Bearer keys (also in .env.example):

npm run shots

1. Governed MCP Gateway

Production MCP drops identity. listTools runs on the request thread; tools/call and SSE run somewhere else. This gateway resolves a Bearer credential to a Principal, injects it on every JSON-RPC call, and repeats it on every SSE frame. Named vault inputs rotate in place — github_token stays github_token.

curl -sS -H "Authorization: Bearer mcp_agt_payops_demo" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"echo.ping","arguments":{"hello":"world"}}}' \
  http://127.0.0.1:7474/mcp

Glama remote connector

Glama can health-check a stateless Streamable HTTP remote at https://$VERCEL_URL/mcp with Bearer auth. This is the hosted HTTPS path. Stdio (npm run mcp / Dockerfile CMD) remains the Glama Docker build path.

Vercel project settings (import this GitHub repo; do not invent a hostname):

npm run build runs scripts/build-vercel.mjs (esbuild). That emits dist/web.mjs. api/index.mjs imports that compiled file — it does not load TypeScript via runtime tsx. Demo allowlist and oversized-schema seed are inlined in that bundle so Fluid does not open test/fixtures/ (the function only includes dist/**). The Other preset still expects a static output folder after a custom buildCommand; public/ is that folder (outputDirectory: "public"). If the Vercel dashboard still has a Build Command of tsc, clear it or set it to npm run build so TS5097 does not come back. Dashboard overrides are not required if vercel.json is honored.

Environment variables (Vercel Project → Settings → Environment Variables). Rotate the demo values before a public URL:

Glama connector fields after deploy (replace $VERCEL_URL with the deployment host Vercel prints):

• URL: https://$VERCEL_URL/mcp
• Transport: Streamable HTTP
• Authorization: Bearer $GATEWAY_AGENT_KEY

Local smoke (no public hostname):

npm run mcp:http:smoke
# or:
npm run gateway
curl -sS http://127.0.0.1:7474/health
curl -sS -H "Authorization: Bearer mcp_agt_payops_demo" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"smoke","version":"0"}}}' \
  http://127.0.0.1:7474/mcp

initialize does not mint Mcp-Session-Id. Pass params.pack / params.need on the same tools/list when you need more than the session pack. GET /mcp is 405 (no sticky SSE on the remote).

2. Agent Spend & Mandate Plane

Agents propose. Mandates authorize. A human countersigns when the amount is over the auto cap. The proposing agent cannot countersign itself. Settlement is a rail: Stripe meter event by default, x402 payment-required if you ask for it. No chain calls in this MVP.

curl -sS -H "Authorization: Bearer spend_agt_payops_demo" \
  -H "Content-Type: application/json" \
  -d '{"agent":"agt_payops","merchant":{"name":"Stripe","url":"https://stripe.com","country":"US"},"total":"12.00","rationale":"tool meter"}' \
  http://127.0.0.1:7475/v1/proposals

3. Auditable CFO Agent Mesh

A board claim is not done until it has an agent, a LOCKED CHP state, and at least one source document hash. Engines measure (ASC 842 lease rollforward, ASC 606 constrained POC, ASC 718 SBC). They do not decide facts of law. Token spend attaches as a source on the same HMAC-chained ledger.

curl -sS -H "Authorization: Bearer cfo_agt_lease_demo" \
  -H "Content-Type: application/json" \
  -d '{"title":"AI spend is $12.00 this period","narrative":"Token ledger supports the board claim.","agentId":"agt_lease"}' \
  http://127.0.0.1:7476/v1/claims
