"How to respond to tagged messages on Slack" matching MCP servers:

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

On-chain delivery receipts for x402 AI-agent payments on Solana: anchors SHA-256 digests of delivered content to a PDA after settlement; buyers verify proof of delivery offline with zero trust in the seller. Live MCP endpoint + npm bridge.

Pay-per-call MCP server for on-chain blockchain data including wallet profiles, token metrics, protocol TVL, and gas prices.

Teaches AI coding agents how to reason correctly about MetaMask Embedded Wallets / Web3Auth architecture, SDK choice, key derivation, auth flows, and common integration pitfalls.

Enables an AI agent to check whether contracts are covered by ERC-7730 descriptors, preview how transactions and typed-data signatures would appear to a person, and simulate execution outcomes before signing, without holding keys or submitting transactions.

Enables MCP agents to create Ink wallets, register ERC-8004 identities, send daily GM messages on gm.ink, and check GM status with dry-run safety and gas gating.

Enables building encrypted, on-chain chatbots on the PFTL network. Allows LLMs to send and receive encrypted messages, register bots, and manage wallet operations.

Enables agents to read and write technocore.chat messages with a did:key identity, including end-to-end encrypted rooms, via 14 tools over stdio.

Enables LLMs to read and write the BSV social graph with an on-chain identity, OS-keychain wallet, and 38 tools for posts, replies, follows, messages, payments, profiles, and more, with every write broadcast as a real BSV mainnet transaction visible across 50+ shared apps.

Enables AI agents to interact with the XMTP decentralized messaging network. Supports sending encrypted messages, managing conversations, and streaming real-time messages to any XMTP-enabled wallet address.

An MCP server for building AI-powered bots and interacting with Solana wallets on the Solafon platform. It enables users to manage messages, check token balances, and handle transactions through natural language in MCP-compatible AI tools.

Enables agents to authenticate and route webhooks from Shopify, Stripe, GitHub, Slack, and PayPal using HMAC-SHA256 constant-time verification and timestamp replay-window validation. It then multiplexes verified events into agent workflows without external runtime dependencies.

Enables AI assistants to query evidence-backed DeFi yield data across roughly 17,000 pools — what each pool pays, whether yield comes from base or reward tokens, and how rates have moved over 7/30/90 days. Every figure is dated and linked to its source, and access is read-only without touching wallet keys.

MCP server for interacting with Letters to the Future on Base mainnet, enabling posting time-locked messages, listing them, minting on-chain SVG NFTs, and checking wallet info via natural language.

Enables MCP clients to act as a did:key identity on technocore-chat's signed lane, allowing signed messages, room claiming, and DID note publishing while keeping the private key out of the model's context.

MCP server for crypto marketing attribution. Build UTM-tagged tracking URLs, estimate campaign ROI, compare web3 attribution tools, and pull DeFi marketing benchmarks.

A minimal demo of the x402 payment protocol protecting an MCP tool endpoint, showing how to charge for MCP tools using real 402 rejections and testnet payments.

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

Enables Claude Desktop, Claude Code, and Claude.ai to interact with a Buzz relay, allowing users to list channels, read/search messages, and post chat events using NIP-98 authentication.

Enables MCP clients to send cryptographically signed messages to Technocore mailboxes and KV state stores as native tools, with automatic did:key signing and atomic state locking.

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.

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.

Exposes nine purpose-built tools for EVE: Frontier on Sui Move, covering Smart Assembly contract coding, Smart Gate route and toll planning, Network Node gigajoule optimization, Smart Turret targeting, killmail threat intel, SSU market making, zkLogin character verification, sovereignty fuel tracking, and PTB drain simulation.

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.

Trust infrastructure for AI agents on Base. DEX Spread Oracle (live Uniswap V3 prices), on-chain escrow, insurance pool, and collective knowledge base. 7 smart contracts. Pay-per-query via x402 micropayments in USDC.

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.

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.
