"Projects and Programs Written in Rust" matching MCP servers:

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

Enables AI agents to interact with Ethereum blockchain by querying ETH and ERC-20 token balances, fetching token prices from CoinGecko, and building/simulating Uniswap V3 swap transactions. Built in Rust with read-only mode by default for safety.

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.

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.

Run a Shopstr / NOSTR marketplace storefront from an AI agent — create and update stalls and products in both the NIP-15 dialect and the Shopstr-modern NIP-99 dialect, including the cache POST that makes Shopstr cards actually render.

Enables AI agents to look up XRPL domain availability, pricing, profiles, portfolios, and transaction status, and to get registration links for signing in the user's own wallet.

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.

PayQL is an MCP server that lets any AI agent query The Graph and pay per query in USDC — gasless, keyless, bring-your-own-wallet.

Local MCP-to-browser signing bridge for EVM, Solana, and Sui, letting agents prepare and simulate transactions while users approve and sign in a browser wallet extension.

DoI oracle for Nostr pubkeys: scores social, vouch, access, and economic-stake dimensions. Returns schnorr-signed cert with per-dim samples. L402-priced at 2 sats. Drop-in for agents needing Sybil resistance.

A MCP server that provides NOSTR protocol tools for LLM agents, enabling signing, publishing, querying, and encrypted DMs with a defense-in-depth safety stack.

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.

A zero-config data server for read-only queries on Robinhood Chain (stock tokens, memecoins, launches, chain stats) and an opt-in trading server with spend caps and confirm gates for executing swaps and transfers.

Connects AI agents and developers to structured blockchain data across multiple networks through Nodit's Web3 infrastructure, enabling easy querying, analysis and interaction with blockchain ecosystems without specialized development expertise.

Decentralized Git with on-chain governance, bounties, and DAOs. Tools for repos, issues, PRs, labels, releases, bounties, and DAO proposals. Auto-wallet on first use, trust tiers, and approval mode for human-in-the-loop.

Identity infrastructure for the agent economy. Mint an agent ~handle in two free calls with no human account, then verify anyone and read inferred traits under the consent the person set in advance.

MCP server for Bags on Solana. Reads token analytics, creator-fee data and trade quotes; executes swaps and fee claims only behind a token gate, a hard SOL spend cap, and a single-use confirmation token bound to the exact arguments. The first call to a write tool signs nothing — it returns a preview. 14 tools, 337 tests at 100% coverage enforced in CI, mainnet-only writes, npm provenance.

Enables natural-language interaction with Solana blockchain data—including network status, wallet balances, transactions, and token supply—via the Helius RPC API in MCP clients like Cursor.

Provides permissionless wallet infrastructure for AI agents to manage wallets, sign transactions, and handle tokens across Solana and all EVM-compatible chains. It includes 29 specialized tools for on-chain operations, featuring built-in security guards and automated x402 payment processing without KYC requirements.
