"npm" matching MCP servers:

The only MCP server that gives AI agents native access to Stacks, Celo, and Base — from a single npm package.

DISCONTINUED (October 2026): the ZPL Engine service is offline, so this MCP server no longer works. Repository archived, npm package deprecated.

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.

Read-only safety checks before an agent acts: scan untrusted text for prompt injection and phishing (locally), check npm packages for malware, hijacked releases and typosquats, scan crypto addresses and tokens, and compare two addresses to catch address poisoning. Zero dependencies.

Hashlock Markets (hashlock.markets) — sealed-bid intent-based crypto trading protocol with HTLC atomic settlement. AI agents can create, commit, and validate trading intents on Ethereum, Bitcoin, and Sui. Canonical npm package: @hashlock-tech/mcp. Not the cryptographic hashlock primitive, not Hashlock Pty Ltd (hashlock.com).

A wallet for AI agents with spending limits: pays x402 and MPP APIs in USDC (Base, Solana, Algorand) and RLUSD (XRP Ledger), checks every payment with presign-guard first, and asks for approval on your phone above your limits. Source in the wallet-mcp folder; npm: presign-guard-wallet-mcp.

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.
