Enables querying indexed blockchain data via subgraph GraphQL queries, part of the Pipeworx MCP gateway.

MCP server that prepares Proof of Invention (POI) transaction requests for submission

An MCP server that lets AI agents autonomously buy physical hats using USDC on Base — no credit card, no checkout, no human required. Browse the catalog, get a real-time shipping quote, send crypto, and we ship the hat.

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.

498 MCP tools across 12 industry verticals. Marketplace, escrow, DeFi, legal, healthcare, insurance, construction, and trades. USDC payments on Base L2.

On-chain crypto indicators (EMA, RSI, VWAP, Bollinger) via Chainlink oracles.

Enables autonomous agents to discover and call 35 pay-per-request microservices — pre-execution security guardrails, smart-contract auditing, Solana token and MEV risk oracles, web research, code sandboxes, and frontier AI models — settling each call atomically via Bitcoin Lightning L402, Solana x402, or Base MPP with no API keys, accounts, or subscriptions. It also offers a zero-token demo mode and drop-in integrations for Claude Desktop, Cursor, ElizaOS, LangChain, and CrewAI.

Enables AI agents to interact with the Lido protocol for ETH staking, position management, and governance participation across Ethereum and L2 networks. It provides tools for querying balances, simulating transactions, and executing complex workflows like withdrawals and DAO voting through a safety-first interface.

Verifies blockchain-anchored timestamp proofs entirely on the user's machine, with five tools: hash a file, verify a file against a proof, verify a known hash against inline proof data, explain what a proof asserts, and create a new proof through ProofLedger. Verification recomputes the SHA-256 and walks the Merkle path locally instead of asking the issuer; only create uses the network.

P2P Crypto and Flashloans. Lets AI agents browse, quote and (optionally) transact with the FlashBank contracts — the P2P term-loan escrow and the flash-loan router — on Ethereum, Base, Arbitrum and the Sepolia playground.

Enables read-only, keyless queries of timestamped, definition-backed data about AI agent payments and activity on Base, including rankings, agent records, detections, metric histories, and evidence-pack pricing, from MCP clients or the terminal.

Enables AI agents to interact with the ProfitPlay prediction market to trade short-term price movements of cryptocurrencies and stocks. It provides tools for market analysis, automated betting, account registration, and leaderboard tracking.

Provides tools and prompts for Bitcoin SV development, enabling code search, BRC lookup, and function definition search within locally cloned BSV repositories.

Enables on-chain attestation of any content onto the DigiByte blockchain, providing permanent, timestamped, tamper-evident proofs. Allows AI agents to notarize their outputs or verify attestations using only the blockchain.

Enables tamper-evident anchoring of file, text, or JSON hashes to the BSV blockchain via MCP tools, with verification and lookup capabilities.

Checks live x402 routes across Base, Solana, and Algorand before agents spend. $0.003 USDC settles only for a valid live eligible route; normal typed misses are not settled. Free preview and validate tools. Seller payment is separate; the agent keeps its wallet. Optional signed route-binding receipts support buyer-side checks.

Provides read-only tools to query live Polymarket prediction-market data via the public Gamma API, enabling search, browsing, and detailed market and event information.

Enables AI agents to make pay-as-you-go AI inference requests through x402 with automatic Solana USDC payments, no API keys or registration, while enforcing configurable spending limits.

Read-only on-chain query surface for the AgentCivics civil registry on Sui — soulbound AI-agent identities, on-chain memories, reputation, refusal records. Hosted, no install, no keypair. For write tools (register, write_memory, record_refusal), install the npm package @agentcivics/mcp-server locally and supply your own keypair.

Live Proof-of-Work mining data for AI agents: difficulty, hashrate, solo-mining odds, cost of production and hardware profitability across 126+ networks and 770+ ASIC/GPU/CPU models. Sourced and timestamped, read-only.
