"An introduction or resources related to MongoDB" matching MCP servers:

Discovers related blockchain addresses and domain names for web3 identities across different platforms including Ethereum, Farcaster, Lens, and ENS using next.id's relation server data.

Generates MCP servers from smart contract ABIs, enabling Claude to interact with any Ethereum contract via natural language commands.

An MCP server that provides authorization middleware for AI agents using private data, enabling consent management on Aleo and local private inference with persistent policy storage.

An AI-driven platform for analyzing Polymarket prediction markets using on-chain data, offering smart money tracking, sentiment analysis, and arbitrage detection via natural language queries.

An MCP server that tracks real-time data for major crypto-related stocks to help AI agents analyze blockchain investment opportunities.

Enables AI agents to access crypto-related information including latest news, prices, and market trends through ChainGPT capabilities.

Enables Claude to interact with the Ethereum Name Service (ENS) system to resolve names, check availability, retrieve records, and perform other ENS-related operations through natural language.

An MCP server for providing semantically related Ethereum Improvement Proposals (EIPs) to AI agents.

Enables MCP clients such as Claude Desktop and Cursor to use an encrypted local x402 wallet for AI agents, with tools to check balance and resources, call paid resources, discover and pay third-party x402 services, quote and execute token swaps, and view history under per-payment and daily caps.

Enables an AI agent to settle HTTP 402-gated resources end-to-end: quote conversions, choose from the seller's accepted rails, sign gasless EIP-712 authorizations under enforced per-call and lifetime caps, and verify settlement receipts while tracking wallet balance. Runs self-hosted over stdio or Streamable HTTP, defaulting to testnet with mainnet requiring explicit confirmation.

Enables agents to discover paid x402 resources, inspect the remaining USDC allowance, and make USDC payments on Solana for API calls from an on-chain delegated budget.

mcp server that allows to do actual actions related to solana first version adds knowledge about RPC methods and how to call them

Enables natural-language-driven on-chain data analysis for TRON blockchain events via MongoDB, allowing AI assistants to query blocks, transactions, contract events, and perform analytics like aggregations, histograms, and address profiling.

An MCP server for AI agents to purchase resources via Stellar testnet USDC, handling quotes, purchase URLs, and merchant receipts.

Enables AI assistants to interact with the Rexi API through a comprehensive wrapper that provides access to all API endpoints with full parameter support. Includes OpenAPI specification resources and schema access for blockchain and contract-related operations.

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.

Enables agents to search and inspect live service offerings, generate x402 payment snippets, and understand blockchain-only balance policies.

MCP server for RugGuard, enabling AI agents to perform pre-trade rug checks on tokens, with paid tools for token scanning and pre-trade verification, and a free metrics resource.

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.

Non-custodial on-chain escrow + AI arbitration for agent-to-agent USDC payments on Base. Seven tools wrap a verified EscrowV1 contract — create, deliver, confirm, dispute, resolve — with read-only introspection if no wallet key is provided.

Let any MCP client issue and verify EU AI Act Article 50 transparency receipts for AI-generated content, anchored to Bitcoin.

Enables MCP-capable agents to retrieve a tamper-evident decomposition of x402 network growth on Base and to place $399 human-reviewed endpoint or wallet audits paid over the x402 rail, without moving funds itself.

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.

Agent-Level Transaction Safety Oracle. Before an AI agent signs a blockchain transaction, it returns a SAFE/UNSAFE verdict with a SENTINEL Score (AAA-D) and risk flags. Pay-per-call $0.005 USDC via x402 on Base.

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.

Enables AI agents to discover and pay for x402-gated HTTP APIs, handling 402 Payment Required flows with local signing. Supports EVM and Solana with non-custodial wallet management.

Keyless crypto payments for AI agents. One MCP call turns any wallet address into a non-custodial crypto payment link or tip jar, no API key and no account, with funds settling straight to your wallet at a 0% platform fee (USDC/USDT, BTC, LTC, DASH, DOGE, ZCASH).

Lets an AI agent hire and pay a verified human: post real-world tasks (voice, observation, judgment) and pay in USDC via a non-custodial x402 auth-capture escrow on Base, budget frozen at deploy. Humans verify their X identity before submitting.

Enables AI assistants to access live mining data for 126+ proof-of-work networks and 770+ hardware models, including network difficulty, hashrate, solo-mining odds, cost of production, hardware profitability, and mining news.
