A watchdog MCP that validates every agent payment request against all 9 security checks before it executes — catching policy violations, replay attacks, amount tampering, revoked tokens, and budget overruns at call time.
merchant_id:amount binding, catching forged or tampered tokenscurrent_spend + amount > budget_cap and returns exact remaining budgetRequires: Python 3.10+, mcp package.
pip install mcp
Claude Desktop — add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):
{
"mcpServers": { "agentpay-sentinel": { "command": "python", "args": ["/absolute/path/to/agentpay-sentinel-mcp/server.py"] } } }
Cursor — add to .cursor/mcp.json in your project root:
{
"mcpServers": { "agentpay-sentinel": { "command": "python", "args": ["/absolute/path/to/agentpay-sentinel-mcp/server.py"] } } }
| Tool | Description | Key params |
|---|---|---|
sentinel_audit_transaction | Run all 9 security checks; returns PASS/BLOCKED + SHA-256 audit hash | token_hash, merchant_id, amount, current_spend, budget_cap (required) · nonce, token_id, approved_amount (enable checks 7–9) |
sentinel_revoke_token | Permanently revoke a token — all future audits with this token_id will BLOCK | token_id, reason |
sentinel_clear_nonce | Remove a nonce from the replay store (for legitimate refunds/retries only) | nonce |
sentinel_verify_chain | Verify a sequence of audit hashes forms an unbroken chain | audit_hashes, expected_chain_root |
sentinel_threat_model | Simulate any named attack vector; returns severity, defence, and detection | attack_vector, context |
sentinel_audit_transaction| # | Check | What it catches | Param |
|---|---|---|---|
| 1 | Token integrity | SHA-256 hash mismatch — forged tokens | token_hash |
| 2 | Budget enforcement | Spend exceeding cap | current_spend, budget_cap |
| 3 | Merchant allowlist | Payment to unlisted merchant | allowlist |
| 4 | Category restriction | Purchase in blocked category | blocked_categories |
| 5 | Expiry check | Expired token | expires_at |
| 6 | Rate limit | Too many calls per minute | calls_this_minute |
| 7 | Amount mismatch | Agent changed amount after human approved | approved_amount |
| 8 | Replay attack | Same nonce used twice (file-backed store) | nonce |
| 9 | Revocation evasion | Agent using a revoked token | token_id |
Checks 7–9 activate when the corresponding param is passed. State persists to ~/.sentinel/.

sentinel_audit_transaction returns an advisory verdict — it does not intercept network traffic. Your agent is responsible for calling it before executing a payment and halting on BLOCKED. The audit hash returned is a SHA-256 digest of all check results, giving you a tamper-evident record of each pre-flight decision.
| Plan | Price | Included |
|---|---|---|
| Free | $0 | 50 audits/month |
| Pro | $19/month | Unlimited audits + threat model simulations |
