"Apache Spark" matching MCP servers:

MCP server for managing on-chain loyalty programs on Base L2. Mint tokens, manage rewards, track balances, tiers and marketplace offers via standard MCP protocol.

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.

Unchallengeable AI agent security audits. MASSAT framework covers all 10 OWASP Agentic Security categories (ASI01-ASI10); audit score 4.3/10 published publicly. Plus the trust layer for the x402 agent economy: ERC-8004 passports, ProofDB delegation chains, on-chain anchoring, x402 + Fedimint payments. Apache-2.0.

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.

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

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.

Provides read-only Solana wallet intelligence for evidence-first copy-trading research, enabling exact wallet activity, parsed swaps, transaction evidence, current positions, token snapshots, source-vs-copy comparisons, watchlist scans, and partial Odin-rule classification.

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.
