"author:alphaparkinc" matching MCP servers:

Enables agents to ingest payment webhooks and ledger transactions with cryptographic HMAC-SHA256 signature verification, sliding-window replay tolerance, and atomic idempotency locking. It also enforces double-entry debit/credit invariants and returns balanced journal records with audit and risk telemetry over MCP.

Enables autonomous financial agents and payment webhooks to create and verify immutable double-entry ledger entries, enforce debit-credit balance invariants, and generate hash-chained audit trails with fraud detection.

Enables autonomous agents to optimize payment recovery by applying decline-code-specific retry windows and reducing involuntary churn through MCP-accessible ledger and fraud-checking workflows.

Enables autonomous detection of recurring charges, price creeping, and zombie subscriptions, then generates automated cancellation workflows through MCP-compatible tools.

Enables autonomous financial agents and payment webhooks to pool corporate treasury cash, rebalance liquidity automatically with yield-optimized sweeps and zero-overdraft safety buffers, and record every transaction in a balanced double-entry ledger with HMAC-SHA256 signature verification and sliding-window fraud detection. Runs as a zero-dependency Python MCP server that plugs into Claude Desktop, Cursor, or any MCP-compliant client.

It enables agents to handle delegated payments and tokenized checkouts while enforcing spend limits, velocity thresholds, merchant whitelists, and issuing ephemeral single-use authorization tokens.

Enables autonomous financial agents to submit payment webhooks, ledger entries, or transaction streams and receive balanced journal records, risk verification dossiers, and detection of card-testing clusters, volume spikes, and account takeovers.

Enables AI agents to broker creator MSA contracts and escrow deliverable milestones through Impact.com, with deterministic, zero-dependency execution and native MCP integration.

Enables multi-party conditional escrow locking, autonomous proof-of-delivery release triggers, referral fee splits, and dispute freeze protection for agentic commerce and enterprise settlement workflows.

Provides a deterministic, zero-dependency MCP server that enforces autonomous merchant checkout token and velocity limits for Agentcard/Stripe transactions, outputting structured guardrail telemetry for agent workflows.

Enables autonomous arbitration of refund and dispute cases by validating carrier proofs and policies through a deterministic, zero-dependency Python engine that integrates with MCP-compliant clients.

Enables AI agents to autonomously issue single-use, merchant-locked virtual Visa cards and execute payments across supported merchants through the Model Context Protocol, with human-in-the-loop approval.

Enables cross-border Geo-IP-based currency conversion and dynamic VAT/tax nexus calculation, integrating with Stripe Tax.
