Haldir vs Vorim MCP Server

A side-by-side look at the Haldir and Vorim MCP Server MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.

Haldir logoHaldirSecurity · Local subprocess (stdio)Guardian layer for AI agents: identity, secrets, audit via MCP.43FairAuth: api key requiredVorim MCP Server logoVorim MCP ServerSecurity · Local subprocess (stdio)AI agent identity, trust, and audit trail infrastructure. 17 MCP tools: register agents with Ed25519 keypairs, check permissions (sub-5ms), emit tamper-evident audit events, verify trust scores (0-100), delegate credentials, and manage ephemeral agents. IETF Internet-Draft filed (draft-vorim-vaip-00). Works with LangChain, OpenAI, CrewAI, Stripe ACP, and 4 more frameworks. npx @vorim/mcp-server.47FairAuth: api key required

Verdict: choose Haldir for security work as a local process; choose Vorim MCP Server for security as a local process. You can also run both side by side in one mcpServers block.
