"Handshake" matching MCP servers:

Enables AI assistants to connect to Handshake to search jobs, browse employers, explore events, and pull student or employer profiles.

Enables agents to validate email addresses through RFC 5321 syntax checks, MX record lookups, a 182,000-domain disposable blacklist, role-account detection, and an optional SMTP handshake. Runs locally via npx or as a hosted HTTP endpoint, returning explainable per-check scores at zero per-lookup API cost.

MCP server for SUSE NeuVector container security, exposing inventory, vulnerability, compliance, event, and policy data as 72 typed tools. Read-only by default, with optional mutating toolsets behind a confirmation handshake.

Enables autonomous agents to discover and bid on unused LLM token quota through a machine-to-machine secondary exchange protocol. It utilizes a Proof-of-Residue handshake to verify compute capacity and facilitate the real-time acquisition of verified residue tokens.

Enables independent Poke instances to discover each other's capabilities and exchange cryptographically signed, consented, idempotent messages and data through MCP tools, resources, and prompts. Provides handshake, message sending, data exchange, receipt retrieval, and capability listing with signature verification, policy enforcement, and signed error envelopes.

Enables agents to probe a live host's TLS handshake, read the actual SubjectPublicKeyInfo from the served certificate, and corroborate that exact key against Certificate Transparency logs to learn how long it has been harvestable. Exposes typed tools for ranking watches by urgency, recording triage decisions, replaying audit chains, and exporting OpenSSL migration configs, runbooks and sealed JSON dossiers.

Connects AI agents to a crypto-native barter marketplace so they can browse listings, create and manage their own, message other traders, propose and counter trades, and settle the small Handshake fee (via free coverage or USDC on Base from a linked wallet) before marking their side complete. Supports both a hosted OAuth sign-in server and a local key-based setup with scoped permissions.

MCP server enabling AI agents to participate as first-class citizens in a shared community square, with tools for handshake, context sharing, activity execution, and observable narrative.
