"Scheduler that invokes the agent based on a predefined schedule" matching MCP servers:

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

Cross-chain cryptocurrency swaps via Chainflip. Get quotes, execute swaps, and track progress. No API key required to get started.

MCP server that checks an x402 paid endpoint before an agent pays it, and checks afterwards that the receipt opens to exactly one real on-chain settlement. Two tools, no account, no API key.

Enables any MCP-capable AI agent to discover and trade onchain Solana funds — launching a fund, depositing, rebalancing, redeeming, swapping tokens, managing an app wallet, and following other traders against the live DFM API. Includes onboarding tools for headless agents and read-only versus write access controlled by an API key and a write-enabled flag.

An MCP server that enables AI agents to interact with the IOTA blockchain, supporting wallet management, transaction signing, and Move smart contract development. It provides tools for on-chain queries and CLI operations with a human-in-the-loop security model.

A stdio MCP bridge for Agent Procurement Manager (APM) that exposes apm_quote, apm_preview, and apm_categories for free supplier quotes, previews, and category discovery. It forwards requests to the hosted APM API; paid procurement runs separately through x402.

Enables agents to publish and search index records with custom keywords over libp2p, connecting to the Agent Index Network for decentralized peer discovery and querying.

A non-custodial RWA service for AI agents on Solana that provides yield comparison, tokenized US-equity quotes, and ready-to-sign transactions.

Enables AI agents to request sign-ins and payments on the Canton Network through a human's mobile wallet, where each request requires explicit human approval and hardware-backed signing.

MCP server that lets AI agents scrape web pages as clean markdown for a micro-payment in USDC, using the x402 protocol on Base network. No API keys or signup required.

An MCP server that audits ERC-8004 agent registrations, diagnosing issues and providing fix lists.

An autonomous MCP server that fetches datasets from IPFS/Filecoin, performs computation (anomaly detection, statistics, data quality scoring), and stores results via Multi-Chain Storage simulation.

Enables users to verify whether an ERC-8004-registered agent is currently reachable by resolving its on-chain registration and performing a live MCP handshake, returning verdicts such as REGISTERED_UNREACHABLE or AGENT_NOT_FOUND.

An MCP server that gives autonomous coding agents deterministic, schema-validated tools for EVM smart contract development — security scanning, gas profiling, compiler diagnostics, and transaction simulation.

Enables AI agents to read and bid on a paid message slot on Solana, with enforced spend limits, dry-run proposals, and an append-only audit log for every write.

On-chain delivery receipts for x402 AI-agent payments on Solana: anchors SHA-256 digests of delivered content to a PDA after settlement; buyers verify proof of delivery offline with zero trust in the seller. Live MCP endpoint + npm bridge.

Reputation scoring for AI agent wallets on Base. 9 tools for trust scores, fraud checks, blacklist lookups, leaderboard, badge generation, and agent registration with x402 payment verification.

Enables AI agents to query blockchain data across EVM chains and Sui through token-efficient MCP tools, including balances, transactions, logs, NFTs, token prices, and Sui objects/events, with optional TORPC tiered ABI decoding.

Pay-per-call MCP server for on-chain blockchain data including wallet profiles, token metrics, protocol TVL, and gas prices.

⚡ 87% Token-compressed clean web scraping, YouTube AI transcripts, and PDF extraction for LLMs. Instant Free Trial with zero setup (No wallet/crypto required). Supports gasless agent vaults and EIP-712 on-chain oracle verification on Polygon, Base & Arbitrum.
