@algovoi/mcp-server

AlgoVoi MCP Server

An MCP (Model Context Protocol) server that exposes AlgoVoi's payment infrastructure as tools any MCP client can call — Claude Desktop, Claude Code, Cursor, Windsurf, or any other MCP-compatible assistant.

Ships as two packages:

Package	Install	Command
TypeScript	npm i -g @algovoi/mcp-server	npx -y @algovoi/mcp-server
Python	pip install algovoi-mcp	uvx algovoi-mcp or algovoi-mcp

Both expose the same 29 tools and the same API surface — pick whichever runtime your client prefers.

29 tools

6	generate_mpp_challenge	IETF MPP 402 WWW-Authenticate headers + challenge_id
7	verify_mpp_receipt	Verify an MPP on-chain receipt
8	verify_x402_proof	Verify an x402 base64 payment proof
9	generate_x402_challenge	x402 X-Payment-Required 402 headers + payload
10	generate_ap2_mandate	AP2 v0.1 PaymentMandate for AI agent payment flows
11	verify_ap2_payment	Verify an AP2 mandate payment receipt
12	try_mpp_endpoint	Probe any URL for MPP/x402 payment requirements
13	discover_resources	Browse the public AlgoVoi payment resource catalogue
14	screen_recipient	Compliance screen a wallet address (sanctions / risk)
15	get_compliance_attestation	Fetch AlgoVoi's live compliance posture document
16	compliance_trust_query	Composite trust verdict (TRUSTED/PROVISIONAL/UNTRUSTED) over a chain of substrate receipts
17	try_mpp_subscription	Probe an MPP subscription URL; parse the 402 subscription terms
18	list_mpp_subscriptions	List a tenant's MPP subscriptions
19	cancel_mpp_subscription	Cancel an active MPP subscription
20–29	(Tier 2 recurring authorities)	create_recurring_authority, get_authority, list_authorities, confirm_authority, revoke_authority, pause_authority, resume_authority, manual_pull + protocol helpers

Supported networks: Algorand, VOI, Hedera, Stellar, Base, Solana, Tempo (USDC on all seven).

Response model — ALGOVOI_MODE

Set ALGOVOI_MODE to choose how much detail tool results carry:

Mode	Behaviour
substrate (default)	Tools return AlgoVoi substrate primitives — action_ref, Ed25519-signed compliance_receipt / settlement_attestation, and the composite trust-query hash + signed ctq_response.
standard	Those substrate-only keys are stripped, leaving the bare x402 / MPP / AP2 standard response shape. The verdict fields (verdict, reasons, trust_outcome, paid) are preserved.

The underlying API always returns substrate fields (they are additive) — standard simply filters them client-side, so you can A/B the two models by flipping one env var.

Two ways to connect

Option A — AlgoVoi Cloud (recommended)

AlgoVoi Cloud is the control plane for all your integrations — WooCommerce, Zapier, n8n, and MCP all in one dashboard. Point ALGOVOI_API_BASE at https://cloud.algovoi.co.uk and your single algv_... API key covers every integration — no tenant ID or payout addresses needed (they're stored in the dashboard).

{
  "mcpServers": {
    "algovoi": {
      "command": "npx",
      "args": ["-y", "@algovoi/mcp-server"],
      "env": {
        "ALGOVOI_API_KEY": "algv_...",
        "ALGOVOI_API_BASE": "https://cloud.algovoi.co.uk"
      }
    }
  }
}

Every payment Claude creates appears in your Cloud dashboard alongside payments from every other platform. One place to see everything.

Sign up free at dash.algovoi.co.uk.

Option B — AlgoVoi direct

Connect straight to the AlgoVoi API with your algv_... key and tenant ID.

Both packages read the same env vars:

Var	Required	Purpose
ALGOVOI_API_KEY	✅	algv_... API key from the AlgoVoi dashboard
ALGOVOI_TENANT_ID	✅	Tenant UUID from the AlgoVoi dashboard
ALGOVOI_PAYOUT_ALGORAND	✅*	Algorand payout wallet address
ALGOVOI_PAYOUT_VOI	✅*	VOI payout wallet address
ALGOVOI_PAYOUT_HEDERA	✅*	Hedera payout account (e.g. 0.0.123456)
ALGOVOI_PAYOUT_STELLAR	✅*	Stellar payout address (G...)
ALGOVOI_PAYOUT_ADDRESS	—	Universal fallback if per-chain vars are not set
ALGOVOI_WEBHOOK_SECRET	—	For verify_webhook
ALGOVOI_API_BASE	—	Override the AlgoVoi API base URL (default: https://api.algovoi.co.uk)
ALGOVOI_MODE	—	Response model: substrate (default) or standard — see "Response model" above

* At least one per-chain address (or ALGOVOI_PAYOUT_ADDRESS as fallback) is required.

Auth is env-var only. Secrets never pass through tool arguments — the MCP client never sees the API key.
