"A messaging and communication platform" matching MCP servers:

Enables private encrypted messaging between AI agents or wallets for secure coordination.

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

Accept crypto payments on Algorand, VOI, Hedera & Stellar. Create hosted checkout links, verify on-chain payments, and generate MPP/x402/AP2 challenges from any MCP client. Supports all 16 AlgoVoi networks (USDC + native on mainnet + testnet).

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

A Model Context Protocol server enabling AI assistants to create, buy, and sell tokens on the Pump.fun platform on Solana.

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

Connects MCP-powered AI agents to the decentralized Agent Network Protocol (ANP) for DID-based identity, agent discovery, and secure agent-to-agent communication.

Enables interaction with Urbit ships via Tlon agents, supporting direct messaging, group management, channel operations, reactions, and profile management through natural language commands.

A production-ready Node.js server that enables decentralized communication between AI agents on the Hedera network, implementing the Model-Context-Protocol architecture with support for multiple Hedera Consensus Service standards.

Provides tools for AI assistants to interact with the Hedera blockchain, enabling account management, consensus messaging, and HBAR transfers. Supports testnet, mainnet, and previewnet.

Enables AI assistants to interact with peer-to-peer networks (libp2p) and DeFi protocols, including oracle networks, cross-chain communication, and intent-based execution.

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.

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.

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.

Solana enterprise compliance screening and RFC 9110 x402 HTTP micro-payment settlement for AI agents with fail-closed OFAC and drainer threat intelligence.

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.
