Boundra — Payment Approval Gateway for AI Agents tools (11)

write = sends, deletes, buys or posts
  • evaluate_paymentFree

    Evaluate a payment intent. MUST be called before executing any payment. ALLOW = you may pay; DENY = you must abandon; ASK = a challenge is returned — relay the reason to the user, then retry with approval_token once the user signs. An optional mandate parameter carries a user-issued single-task authorization.

  • get_audit_trailFree

    View recent payment-approval audit records for an owner

  • get_policyFree

    View the active signed payment policy for an owner (and optionally an agent scope)

  • get_policy_versionsFree

    View a user's policy version history (version chain + hashes, verifiable against on-chain commitments)

  • get_spend_reportFree

    View today's spend summary for an owner

  • list_policy_requestsFree

    List pending agent policy-change requests

  • list_templatesFree

    List policy templates (personal assistant / travel / dev API / procurement)

  • render_templateFree

    Render a natural-language rule from a template + parameters (then compile, sign & publish)

  • request_policy_changeFree

    [For agents] Ask the user for a policy/budget change (e.g. 'raise daily budget from 50 to 80'). The request is queued for user approval; the user signs and publishes a new policy version. Agents can NEVER change policy directly.

  • revoke_policyFree

    [USER ONLY] Revoke a policy chain (takes effect immediately; subsequent payments default to DENY). Must carry the user's wallet signature over the revocation statement.

  • set_policyFree

    [USER ONLY] Submit a new policy version. Must carry the user's wallet EIP-191 signature over the policy document; accepted only after signature + version-chain checks pass. Agents MUST NOT call this tool.

Boundra (boundra.io) — Boundaries for agent payments.

The boundary layer for agent payments: before any money moves, answer

"should this payment happen at all?"

Our thesis: the opportunity in agent payments is not "how to pay" (protocols solved that) but "whether to pay."

One natural-language rule → compiled into a policy → every payment the agent attempts is genuinely evaluated → allow / ask a human / veto, with a full audit trail.

Two run modes:

and wallets, zero dependencies, zero network

  • Offline simulation (demo.py): stdlib only, self-contained mock merchant

Base Sepolia testnet

  • Real protocol (demo/demo_real.py): standard MCP server + real x402 SDK +

Data flow

Policies and keys stay with the user; the gateway is read-only; only hash commitments go on-chain. Revocation is free — forever, no exceptions.

Integrating Boundra into your agent? See

docs/INTEGRATION.md — hosted API, x402 SDK hook,

and MCP paths with tested code.

See it run in 60 seconds

# 1. Hit the hosted evaluation API — a real, public x402 merchant
curl -X POST https://api.boundra.io/evaluate/basic \
  -H 'Content-Type: application/json' \
  -d '{"intent":{"amount":0.01,"recipient":"api.weather.com","purpose":"weather data"}}'
# → {"decision":"ALLOW",...}  ·  semantic layer: 100 free calls per agent,
#   then $0.003 via x402 — settled for real on Base mainnet (USDC)

# 2. Local end-to-end simulation — a data-procurement agent's day
.venv/bin/python demo/simulate_agent.py
# signed policy publish → ALLOW / DENY (limit) / ASK → user-signed approval token
# → prompt-injection blocked → audit trail, plus a dogfood call to api.boundra.io

# 3. One-line MCP install + 2-minute policy wizard
uvx --from git+https://github.com/gobeyondfj-cmd/boundra boundra-mcp     # stdio server
uvx --from git+https://github.com/gobeyondfj-cmd/boundra boundra-init    # wallet → template → sign → anchor
uvx --from git+https://github.com/gobeyondfj-cmd/boundra boundra-approve # sign an ASK challenge

The complete flow, step by step

Zero to a signed, enforced policy in ~10 minutes. No accounts, no dashboards — your wallet key is your identity.

0 · Try the hosted API (30 seconds, nothing to install)

curl -X POST https://api.boundra.io/evaluate/basic \
  -H 'Content-Type: application/json' \
  -d '{"intent":{"amount":0.01,"recipient":"api.weather.com","purpose":"weather data"}}'

1 · Bind your identity — the wallet is the account

uvx --from git+https://github.com/gobeyondfj-cmd/boundra boundra-init

Creates or imports a Base wallet. No signup, no email — the private key never leaves your device, and your address is your identity everywhere in the system.

2 · Set your policy

The wizard offers templates (personal assistant / travel / dev API / procurement) or lets you write your own rule in plain English, then compiles it and shows you exactly what will be enforced — before anything is signed.

3 · Sign & publish

You sign the policy document with your wallet key (EIP-191). It is published as a versioned document and a hash commitment is anchored on-chain. From this moment the gateway is read-only for every agent — changing the policy without your key is impossible.

4 · Mount the MCP server into your agent

Hosted (zero install, multi-tenant, default-deny until you publish a signed policy):

{ "mcpServers": { "boundra": { "url": "https://api.boundra.io/mcp" } } }

Or self-hosted:
