"Connecting a backend project to an Elasticsearch database" matching MCP servers:

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

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

Enables AI agents to play the CPU Game on EVM, including world exploration, building, crafting, and trading via natural language.

A Model Context Protocol (MCP) server connecting AI agents to the Polygon blockchain for product origin verification and supply chain timeline auditing

A Model Context Protocol server that allows AI assistants like Claude to directly query cryptocurrency and blockchain project data from RootData, including project information, organization details, and search results.

A backend service for executing transactions on Binance Smart Chain, enabling secure transfers of BNB and BEP-20 tokens, smart contract interactions, and token creation through structured MCP integration.

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.

Enables AI agents to fetch machine-readable real-world asset tokenization data—including project verification verdicts, scored projects, issuances, licences, regulatory updates, and market snapshots—through x402 per-call paid, read-only MCP tools, with each record carrying an official source URL and verification date.

Enables AI agents to discover, call, and pay for existing HTTP APIs over MCP with x402 paywalls, non-custodial settlement, and no code changes to the backend.

A backend MCP server that enables AI agents to publish, validate, and search research papers, submit swarm-compute jobs, and invoke formal proof checking on the P2PCLAW decentralized network.

A backend service that executes transactions across multiple blockchains, enabling users to manage wallets, transfer tokens, and interact with smart contracts using the Model Context Protocol framework.

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 wallet signature and track the transfer. Base, Arbitrum, Ethereum, Polygon, Avalanche, BNB Chain, HyperEVM, Robinhood Chain, Solana and Tron.

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.

MCP server for Pi Network that enables AI agents to query Pi chain data (balances, transactions) and verify user tokens, with optional payment sending that is off by default.

Enables LLMs to interact with the AT Protocol ecosystem, including Bluesky, through natural language. Supports public data access without authentication and full write operations with authentication.

An MCP server that enables cross-chain token transfers via the Stargate protocol.

MCP server that enables AI signing agents to pre-flight transactions by checking ERC-7730 descriptor safety, explaining function semantics, and scanning contracts for danger primitives.

Provides Web3 founders with tools for project scoring, portfolio matching, fund matching, hackathon discovery, jurisdiction analysis, Twitter audit, and smart contract security review. Works with MCP-compatible assistants without transmitting file contents.

MCP server that builds unsigned Paraswap token swap transactions for self-custody wallets, holding no keys and signing nothing. It returns raw transaction data for a human to review and approve before execution.

Lets AI agents check whether an EVM wallet address carries an EIP-7702 delegation across eight chains (Ethereum, Base, BNB Chain, Arbitrum, OP, Polygon, Gnosis, Unichain) and learn how to obtain a deeper paid report with delegate bytecode heuristics and risk levels. Read-only, never touching private keys or seed phrases.

MCP server for OrcaTrace, a pay-per-call Polymarket intelligence feed for AI agents. It provides tools to track smart money, whale entries with calibration, market repricings, and digests across 42K prediction markets, with payments settled via x402 on Base.

Provides live cross-DEX market data on six EVM chains, including per-venue prices, liquidity, and gross spreads with optimal trade sizes. Enables AI agents to query real on-chain data for BSC, Polygon, Arbitrum, Base, Avalanche, and Optimism via MCP tools.

Provides AI agents with direct access to the Ray Group DeFi UX rubric, named patterns, and cognitive-bias glossary for grounded UX assessments of DeFi protocols.

Gives MCP-compatible LLM agents direct access to real-time MEV and DeFi data via Valorem's x402-paid API endpoints, with payments in USDC on Base mainnet.

WaxSeal MCP gives AI agents cryptographic identity — verify any WaxSeal fingerprint, check Ed25519 signatures, and gate irreversible actions with human-signed approval tokens before execution. It connects Claude Desktop, Cursor, and Windsurf to the WaxSeal trust network so agents can prove who authorized an action and reject tampered credentials in under a second.

DexPaprika MCP server allows LLMs to access real-time and historical data on tokens, DEX trading activity, and liquidity across multiple blockchains. It enables natural language queries for exploring market trends, token performance, and DeFi analytics through a standardized interface.

Enables checking whether a crypto link is a phishing lookalike of a wallet, exchange or dapp by comparing it against official domains and flagging lookalike characters, typosquats, punycode and bait words, fully offline. An optional paid full check adds domain registration age, DNS, redirect tracing and a page scan for seed-phrase prompts and drainer code.

An MCP server that provides real-time web search to AI agents via a pay-per-search USDC microtransaction system.

Enables LLMs to compile and verify Tolk smart contract code for the TON blockchain.
