Enables AI assistants to search campaigns, view agent profiles, and build funding transactions on the Clawsfund Solana crowdfunding platform.

Autonomous M2M compliance and trust APIs for AI agents (KYB, OFAC, VAT, Sanctions checking).

Provides AI agents with 200 deterministic micro-services covering code auditing, 3D/robotics, media processing, cryptography, blockchain settlement, AI safety, networking, and math, with automatic x402 USDC micropayments.

Provides AI agents direct access to the Chainstack platform, enabling blockchain node deployment, documentation search, platform status checks, and more.

Enables ChatGPT to interact with multiple blockchain networks for reading balances and managing wallet operations through a non-custodial local vault and policy engine.

MCP server that enables AI agents to simulate EVM bytecode and probe capabilities, serving as a gateway to an Ethereum execution engine.

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

Enables agents and humans to pay per question over x402 and receive plain-language answers about on-chain activity, priced by complexity before execution. Each paid request runs a live subgraph round trip to search, validate, generate and execute a GraphQL query, then synthesizes the raw results into a grounded response alongside the underlying data.

An autonomous self-healing and chaos-resilient agent operations platform for KeeperHub, enabling fault injection, transaction self-healing, and onchain job management via MCP v1.0.

An enterprise-grade MCP server platform for executing real DeFi operations on Solana and EVM chains using natural language. It enables users to perform live trading, volume generation, and wallet management directly within Claude Desktop.

MCP server for vyne, a Solana DeFi automation engine, enabling creation, testing, and monitoring of multi-step workflows via 32 tools, 11 resources, and guided prompts.

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.
