Rescues USDC, USDT and USDG from wallets with no gas. Agents check a wallet for stuck or frozen stablecoins, quote a send or a swap into the gas coin, collect the user's wallet signature and track the transfer. Fees come out of the amount, and nothing moves without the user's signature. Base, Arbitrum, Ethereum, Polygon, Avalanche, BNB Chain, HyperEVM, Robinhood Chain, Solana and Tron.

Provides Web3 founders with tools for project scoring, portfolio matching, fund matching, hackathon discovery, jurisdiction analysis, Twitter audit, and smart contract security review. Works with MCP-compatible assistants without transmitting file contents.

Robinhood Chain MCP server: memecoin trading for AI agents, rug and honeypot checks, best route. Enables AI agents to discover screened new Robinhood Chain tokens, quote swaps across multiple routers, and prepare buy or sell transactions for wallet signing without holding funds or keys.

Generate crypto QR codes (BTC, ETH, SOL, USDC, USDT, EURC) and manage payment sessions from Claude Desktop or any MCP client. Non-custodial, free.

Provides MCP tools to query Etherscan for Ethereum blockchain data—ETH balances, ERC-20 tokens, transactions, contract ABIs, and gas prices—without requiring an API key.

Enables blockchain AML screening of addresses in plain language inside any MCP client, covering sanctions and freeze checks, risk scoring, fund tracing, and counterparty classification across bitcoin, ethereum, bsc, and tron. Works without an account, with an optional API key that lifts rate limits and unlocks outgoing tracing.

Enables AI agents to obtain plain-text Solidity call-flow analysis, including entry points, call trees, reachability, unresolved calls, and interface bindings, so they can inspect and quote contract flows without a web UI.

Enables any agent to purchase Claude and Grok inference metered per token, settled in BSV, via the hosted gateway without holding keys or running models locally.

An MCP server that mints STAS, DSTAS, and BSV-21 tokens into a BSV Desktop wallet in seconds, enabling rapid token testing and development.

Zero-knowledge proof generation MCP server. AI agents can prove identity claims (Coinbase KYC, Country, Google OIDC, Google Workspace, Microsoft 365) without revealing personal data. Runs in AWS Nitro Enclave TEE with x402 USDC payments.

Read-only MCP server that enables natural-language queries about Solana NFTs, including ownership history, freeze/burn rights, marketplace sales and floors with source and currency, directly from the chain and marketplaces without sign-up.

Read-only on-chain intelligence for AI agents on Base, providing tools to read balances, token metadata, gas, and transaction status live from chain without API keys.

Enables signing statements and registering them on a Forestrie transparency log under a held grant, then waiting for the seal and verifying the receipt. It can also issue child grants and pay canopy's x402 charge within configured caps or relay payment requirements.

Enables an agent to fetch the material a separate verifier checks — receipts, genesis documents, univocity accumulator snapshots, registration statuses and SCITT service configurations — from a SCRAPI base URL or a chain RPC endpoint you supply. Every result reports where its bytes came from and which trust-model questions they can answer, without ever choosing an operator or chain provider for you.

Provides search, trending, odds, arbitrage, and category browsing for prediction markets (Polymarket & Kalshi) via the Model Context Protocol, enabling AI agents to access live market data without API keys.

Enables MCP clients to get swap quotes and calldata on Robinhood Chain with equity-aware guardrails such as oracle fair-price checks and market-hours warnings, without holding keys or executing transactions.

Gives MCP agents sealed, recomputable crypto market intelligence from three engines plus Market Scan: asset insights, batch signals, trading-pair signals and a market ranking. Every PRO answer carries a SHA-256 protocol hash. Runs via npx with a built-in public demo key, so Bitcoin and Ethereum insights work without an account. It does not execute orders.

Query recent blockchain address data (last 14 days) for EVM, UTXO, Solana, XRP, and Kaspa networks without requiring address sync.

Enables AI agents and terminal users to discover Solana Gibwork bounties, inspect deliverable requirements, verify on-chain escrow and token mints, and scaffold local development workspaces.

Enables reading and analyzing deployed EVM smart contracts by fetching bytecode, disassembling with invalid jump detection, reading storage, deriving Solidity storage slots, and decoding calldata on any EVM chain without an API key.

Enables interaction with the DorkFi lending protocol on Voi and Algorand, supporting market discovery, position queries, liquidation scanning, and transaction preparation without signing or broadcasting.

An MCP server for Minuet — the relationship layer for ERC-8004 AI agents. Exposes Minuet's read-only API as a set of MCP tools so any MCP-compatible client (Claude Desktop, Cursor, Cline, etc.) can query the ERC-8004 agent relationship graph natively.

The MCP gateway that lets any AI agent discover and pay metered APIs on Base or Solana — without the user wiring payments themselves.

Enables agents to query live Robinhood Chain data including tokens, wallets, Chainlink feeds, heat scores, and tracking error on tokenized equities, all read-only without API keys.

Reasoning-puzzle arcade for AI agents with seven generated puzzle families, free samples, automatic answer checking, and ranked play from $0.02 USDC on Base via x402. Connect through MCP or HTTP. Browse and try samples without a wallet; run paid tools locally with an explicit spending limit.

Algorand ecosystem knowledge layer as an MCP server, enabling identification of applications and assets, protocol discovery, name resolution, and protocol summaries without on-chain queries.

Enables AI agents to discover verified B2B lead packs and obtain exact x402 payment terms plus a step-by-step buying flow from inside MCP clients, without moving funds or holding keys.
