"3D content, models, or technology" matching MCP servers:

Enables interaction with the Cork DeFi protocol for reading live chain state, computing bit-exact math, building unsigned bundles and orders, and managing markets, all without signing or broadcasting.

Enables AI assistants to interact with the Xian blockchain, including wallet management, token transfers, smart contract operations, DEX trading, and indexed blockchain data queries through a unified MCP and HTTP interface.

Pay for any x402-gated content or API with USDC micropayments on Base. Discover payment gates, execute payments, and view transaction history.

Enables on-chain attestation of any content onto the DigiByte blockchain, providing permanent, timestamped, tamper-evident proofs. Allows AI agents to notarize their outputs or verify attestations using only the blockchain.

A bridge that enables AI language models to publish content to the Nostr network by implementing the Model Context Protocol (MCP).

Enables AI models like Claude or GPT to interact with a decentralized git network, supporting repository initialization, DID generation, agent spawning, and pull requests.

Enables AI applications to interact with the COTI blockchain for private token operations, supporting account management, private ERC20/ERC721 tokens, and secure transactions using Multi-Party Computation (MPC) technology.

Enables AI applications to interact with the COTI blockchain for private token operations, including deployment and management of private ERC20 tokens and ERC721 NFTs using COTI's Multi-Party Computation (MPC) technology.

Hashlock Markets — sealed-bid intent-based crypto trading via MCP for AI agents. Atomic cross-chain settlement (Ethereum, Bitcoin, Sui) using HTLC. Six MCP tools for RFQ price discovery without information leakage and HTLC settlement without escrow or bridges. Canonical npm: @hashlock-tech/mcp.

MCP server for local transaction signing across EVM, UTXO, Tron, and XRP blockchains, with no network calls or API keys required.

Enables cross-chain swap execution across 12 venues and 17 chains, including native Bitcoin as source or destination, with tools for quoting, execution, status, and health checks. No signup, API key, or protocol fee required.

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.

Enables AI agents to interact with a Liquid network wallet, including balance checks, transaction history, and sending L-BTC or Liquid assets. Backed by an in-process LWK wallet, requiring only a mnemonic, with both stdio and HTTP support.

Cross-chain bridge aggregator MCP server for AI agents. Compares routes across LI.FI, deBridge, Relay, Across and Squid to find the best rate. Use when an agent needs to bridge or swap tokens between EVM chains, Solana, or Cosmos. The aggregator of aggregators.

A read-only MCP server for safely exploring Nostr, enabling agents to resolve identifiers, fetch profiles and events, query notes, and inspect relay metadata. It does not accept private keys or publish events.

Thin MCP wrapper around the SQD Portal API for blockchain data queries across multiple networks including EVM, Solana, Bitcoin, Substrate, and Hyperliquid. Provides 25 public tools for discovery, cross-chain queries, and chain-specific operations.

A self-hosted decision engine that sits between an AI agent and blockchain execution. Agents submit a proposed action, Guardian returns an explainable ALLOW / WARN / BLOCK before anything gets signed or broadcast.

A wallet for AI agents: test funds, payments, paid APIs and escrow on Aether. Give an AI agent its own wallet on Aether, a proof-of-work chain with post-quantum (ML-DSA-44) signatures. The agent gets an address and testnet funds in one step, then sends and receives AETH or USDC under per-payment and daily limits you set. It can pay for APIs that answer HTTP 402, sell its own, rate the services it

Enables users to compare current Aerodrome veNFT voting positions, bounded claimable rewards, and selected pools' voting evidence on Base against a saved local baseline, with retryable, atomically stored change reports. All tools are read-only on chain, requiring no keys, signing, or transactions.

Provides access to 70 paid APIs as MCP tools with per-call and session budgets, paying via x402/USDC on Base without requiring an account or login. Includes a built-in allowlist of hosts and safe defaults to prevent unintended payments.
