"Connecting Feishu (Lark)" matching MCP servers:

MCP server connecting AI assistants to Havona trade finance API for managing trade contracts, checking blockchain status, and extracting document fields.

A read-only MCP server connecting AI agents to MTRKR wallet intelligence on MegaETH, enabling wallet portfolio, DeFi positions, security scanning, and transaction analytics.

A Model Context Protocol (MCP) server connecting AI agents to the Polygon blockchain for product origin verification and supply chain timeline auditing

Provides read-only access to live Hylo protocol data on Solana mainnet, including hyUSD/xSOL/eHYUSD mint supplies, pause flags, Earn Pool NAV and pool holdings, and an address's direct SPL token balances for those mints. It answers queries and explains the core mechanism without connecting a wallet, building transactions, or signing anything.

Enables MCP clients to optimize Uniswap v3/v4 tick ranges by balancing fee APY against impermanent loss under asset volatility, while providing L2 orderbook imbalance, triangular arbitrage, and Bayesian portfolio rebalancing analytics.

Enables AI agents to prove knowledge of a private key through a three-pass commitment, challenge, and response exchange, paired with SHA-256 Merkle inclusion proofs, JWT HMAC-SHA256 claim validation, constant-time secret comparison, and sliding-window nonce replay protection. Runs as a zero-dependency JSON-RPC 2.0 stdio server compatible with Claude Desktop, Cursor, and Windsurf.

Non-custodial 2-of-3 Bitcoin escrow for AI agents. Two agents agree on signed terms, the buyer funds over Lightning, the seller delivers and gets paid over Lightning, and a neutral arbiter key only breaks ties.

Post-quantum document anchoring for AI agents. Anchor any SHA-256 hash to Algorand mainnet with ML-DSA-65 (NIST FIPS-204) signatures and receive a self-contained proof bundle verifiable offline — decades from now, without trusting any vendor.

Enables monitoring honeytoken decoy private keys for mempool activity, detecting and alerting on potential intrusions.

Enables creating and verifying permanent, publicly verifiable content provenance stamps via MCP tools.

Enables agents and audit systems to hash execution logs into tamper-proof Merkle trees, compute cryptographic inclusion proofs, and verify audit-trail integrity on demand. It runs as a zero-dependency Python MCP server (stdio JSON-RPC) or as an importable module, exposing anchoring, proof generation, and integrity verification over local agent activity records.

Enables auditing EIP-712 typed signature phishing permits and sanitizing allowances (Permit2/MetaMask) via MCP, with deterministic callgraph verification and DeFi vulnerability triage. It integrates with Claude Desktop, Cursor, and MCP clients for autonomous smart contract security analysis.

Enables static auditing of EVM Solidity smart contracts to detect critical vulnerabilities such as reentrancy state changes, unhandled external calls, unchecked delegatecall, and tx.origin authentication flaws, producing risk audit reports.

Enables automated EVM flash loan arbitrage risk assessment and MEV sandwich attack protection for Aave and Uniswap v3, offering deterministic slippage and vulnerability analysis through the Model Context Protocol.

Enables automated Solidity smart contract auditing by analyzing callgraphs and control flow to detect reentrancy vulnerabilities. Integrates with MCP-compatible clients to provide deterministic, zero-dependency security assessments.

Enables automated auditing of cross-chain bridge token reserves and monitoring for anomalous outflows on LayerZero and Wormhole, integrating with MCP-compliant clients for deterministic Web3 security analysis.
