"Hive" matching MCP servers:

Encrypted secret store for the A2A network — Hive Civilization. Agents can store and retrieve secrets encrypted with AES-256-GCM, scoped to their DID, with USDC payment via x402.

MCP server for Hive Passport, enabling lookup of HKTN registry records, zone membership proofs, and A2A clearance integration.

Provides TSS-MPC key splitting and ZK biometric commitments for secure key custody, now suspended per partner doctrine.

Reference implementation of HiveAttest claims for autonomous agents, exposing 19 tools for attestation, custody, cargo, warranty, and gate evaluation with real Ed25519 signatures.

Pre-attestation gate for AI inference that checks compliance conditions and issues Ed25519-signed clearances before execution, refusing any inference without a valid clearance.

W3C DID resolution and agent KYC for autonomous agent counterparties, enabling identity verification and trust scoring.

Enables AI agents to sign and verify actions with ML-DSA-65 digital signatures, providing tamper-proof receipts that can be verified offline without any secrets.

Bridges Holepunch/Keet identity keys into the Hive DID network, enabling DID resolution, attestation verification, and partner lookup via MCP tools.

Enables AML screening of blockchain addresses against OFAC SDN lists and chain heuristics, returning risk scores and flags.

Routes blockchain address screening to third-party KYC/AML providers and checks public sanctions lists, serving as a clean-money gate primitive for MCP-compatible agents.

Pre-settlement on-chain address risk screening for autonomous agents, using GoPlus 17-vector analysis and returning Ed25519-signed attestation receipts.

KYA (Know Your Agent) identity, trust scoring, and insurance protocol for autonomous AI agents. Issues verifiable credentials, computes real-time trust scores, and provides agent liability coverage on Base L2.

Enables MCP clients to query the ransomware.live PRO threat-intelligence API through 25 read-only tools covering ransomware group TTPs, victims, IOCs, YARA rules, ransom notes, leaked negotiation chats, press coverage, SEC 8-K disclosures, and CSIRT contacts.

MCP server for Ransomware.live API - Real-time ransomware victim monitoring

A Model Context Protocol (MCP) server that provides integration with the Have I Been Pwned API to check if your accounts or passwords have been compromised in data breaches.

GATE verifies whether an AI agent still has valid delegated authority at execution time. It supports live revocation, signed authority events, alternate delegation paths and fail-closed decisions. Open-source MCP server with a Free managed-network Developer Preview.
