Enables AI trading agents to query a multi-layer pre-trade risk firewall that evaluates market regime, pair directives, liquidity-trap microstructure, and deterministic ALLOW/VETO verdicts before perpetual futures entries using real on-chain telemetry.

Enables AI agents to create and manage contract-guarded USDC wallets on Base with enforceable per-payment, daily, and monthly caps, vendor allowlists, escalation thresholds, and freeze controls. It provides read-only policy checks plus unsigned transaction proposals for payments, funding, vendor management, wallet creation, and module deployment without holding keys or broadcasting.

MCP server providing real-time crypto prices (Chainlink + Binance), Polymarket prediction market data, deep web research, and JS-rendered web scraping. All services available via x402 Solana micropayments.

Pay-per-task AI agent for writing, research, code, DeFi & blockchain. Pay in USDC on Base or Solana. Supports A2A, MCP, x402 and Agentmail protocols.

MCP server for Chainlink Runtime Environment, enabling build, simulate, deploy, and manage CRE workflows from any MCP client.

A Model Context Protocol server that enables Claude AI to interact with the Solana blockchain, allowing it to execute transactions, query accounts, manage wallets, get price predictions, trade tokens, and access various blockchain data sources.

Enables static security audit of Solidity smart contracts by analyzing source code or deployed bytecode for vulnerabilities, providing risk scores and detailed findings.

Agent tools for the Ophis intent-based DEX: parse, quote, build, relay orders, look up fee tiers.

Enables AI agents and scripts to rug-check any token on Base, Ethereum, Arbitrum, Optimism, Polygon, or Solana, returning a 0-100 risk score with plain-language reasons and a fingerprint for detecting changes on later checks. It also reports market data and supports automatic $0.01 USDC payments via x402.

Provides post-deploy Solana threat intelligence, enabling AI agents to check operators, tokens, and network stats for detecting rug pulls and malicious activity.

Provides read-only tools for discovering, analyzing, and monitoring Hyperliquid HIP-4 prediction markets (outcome trading) on testnet.

9 tools, Lightning-gated. Pay per call. For agents that need verifiable signed actions with an audit trail. Nostr event signing via daemon Publish events to relays Create Lightning invoices Action receipts — signed proof of agent actions Identity attestation

A cross-chain bridge security auditing toolkit that exposes tools for analyzing, fuzzing, and simulating bridge contracts via natural language, enabling users to detect vulnerabilities like centralization risks and replay attacks.

Enables AI agents to send ETH and tokens, approve token spending, and make contract calls while every transaction is decoded, simulated, checked against policy, threat lists, and user intent, with suspicious actions blocked or escalated for human approval.

Enables interaction with the Magic Eden NFT marketplace across multiple blockchains, providing tools for browsing collections, managing NFTs, analyzing portfolios, and detecting arbitrage opportunities through natural language.

MCP server for declarative intent execution. Agents submit intents — transfers, swaps, multi-hop routes — and the engine resolves and executes them atomically.

Enables access to Polymarket's prediction markets for analyzing market probabilities, trading activity, and event outcomes across politics, sports, crypto, and other categories through natural language queries.

Enables AI assistants to interact with peer-to-peer networks (libp2p) and DeFi protocols, including oracle networks, cross-chain communication, and intent-based execution.
