"Using Laravel Helper Functions and Resolving MySQL Table Query Errors" matching MCP servers:

A Model Context Protocol server providing tools for querying Bitcoin blockchain data via Blockchain Data and Query APIs, supporting various BTC information retrieval functions.

Exposes Base mainnet chain query tools over MCP, letting clients fetch an address's native balance and current gas fee estimates (slow/standard/fast urgency) from an upstream HTTP API. Paid tools are gated by x402 micropayments settled through the CDP facilitator, with a free health check and a documented free-trial allotment.

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

Provides MCP tools to disassemble Kaspa scripts, estimate compute costs, explain txscript errors, and look up opcodes.

Enables AI assistants to query blockchain data across 30+ networks via Infura, using natural language for blocks, transactions, contracts, and more.

Inspects and debugs Solana transactions, accounts, Anchor IDLs, errors, and PDAs from MCP-compatible clients.

Facilitates interaction with Starknet blockchain via MCP by exposing various RPC methods, allowing users to query chain states, transaction details, and block information using natural language queries.

Enables querying blockchains across EVM, Solana, Bitcoin/UTXO, and Cosmos through a unified interface, with tools for resolving addresses, checking balances, fetching transactions and blocks, reading contracts, decoding calldata, and building unsigned transfers.

Query blockchains with plain English — instant, structured, and developer-friendly using Infura APIs

Query the Sui blockchain directly from Claude using GraphQL.

Simulates EVM transactions against forked chain state and explains why they revert, using Tenderly's free-tier API with decoded traces and source-mapped errors. Provides tools to simulate single transactions or bundles and inspect saved simulations, all with output size controls to keep responses affordable.

Enables resolving ENS names to Ethereum addresses and profile records, and reverse-resolving addresses to ENS names, all without requiring an API key.

Provides complete HTTP/JSON access to all 100+ Emercoin RPC endpoints with integrated formatting utilities. Enables blockchain operations, name system management, wallet functions, and mining operations through a comprehensive REST API interface.

Enables Claude to increment and query a counter deployed on the Linera blockchain via natural language, using an Apollo MCP server bridge.

A Model Context Protocol (MCP) server that provides onchain tools for Claude AI, allowing it to interact with the Polygon PoS blockchain to call contract functions, manage ERC20 tokens, and check gas prices.

A Model Context Protocol server that enables AI assistants to access Flow blockchain data and perform operations such as checking balances, resolving domains, executing scripts, and submitting transactions.

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.

Enables AI agents to discover, purchase, and query blockchain-based datasets using Filecoin/IPFS storage with Ethereum NFT access controls and Lit Protocol encryption. Provides a decentralized marketplace for secure dataset trading with automatic purchase workflows and SQL query capabilities.

Read-only on-chain query surface for the AgentCivics civil registry on Sui — soulbound AI-agent identities, on-chain memories, reputation, refusal records. Hosted, no install, no keypair. For write tools (register, write_memory, record_refusal), install the npm package @agentcivics/mcp-server locally and supply your own keypair.

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.
