"Replicating ChatGPT Memory Functionality for Task Management and Skill Tracking" matching MCP servers:

Persistent memory and payment safety for AI agents on Lightning. Enables agents to remember purchases, track vendor reputations, enforce budgets, and share trust signals via Nostr.

Enables time tracking and invoicing through natural conversation with MCP clients like Claude or ChatGPT, allowing users to log work hours, query unbilled time, and draft invoices, with a minimal web app for settings, CSV import, and Stripe-powered billing.

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

Enables agents to monitor transaction streams, detect recurring charges and price creeping, flag zombie subscriptions, and generate automated cancellation 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 refund and dispute arbitration by validating carrier proofs and policies, producing structured output dossiers with execution telemetry.

Enforces autonomous merchant checkout token and velocity limits for Agentcard/Stripe transactions.

Discover audio and LLM services, compare seven voices, and check prices for free. Generate speech, transcribe audio and request LLM text with optional capped USDC payments on Base; voice-cloning requirements are also available.

Credit and payments for AI agent developers — over MCP. No crypto required

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 to pool corporate treasury cash, rebalance liquidity, and optimize yield sweeps while enforcing double-entry ledger integrity, HMAC-SHA256 signature verification, and fraud-detection safety buffers that prevent overdrafts. Runs on pure Python standard library and plugs into MCP clients such as Claude Desktop, Cursor, and Windsurf.

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.

Enables autonomous financial agents and payment systems to analyze transaction streams in real time, detect velocity-based fraud patterns such as card testing, volume spikes, and account takeovers, and produce balanced ledger records with audit telemetry.

Enables autonomous financial agents to optimize payment recovery by analyzing decline-code retry windows and mitigating involuntary churn, while enforcing balanced double-entry ledger records, HMAC-SHA256 signature verification, and sliding-window fraud detection through an MCP-compatible interface.

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 users to connect bank accounts within a chat session using Sophtron's UCW widget and query account information, owner details, and transactions persistently.

USDC payments for AI agents on Base. Direct transfers, pre-funded tabs, x402 paywall handling, and service discovery.

Enables MCP clients and autonomous financial agents to submit payment webhook events, journal entries, or transaction streams and receive cryptographically verified, balanced double-entry ledger records with HMAC signatures and hash-chained audit telemetry. It enforces debit/credit invariants and supports fraud detection for real-time accounting workflows.

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.
