Heimdall MCP: MCP server, setup and security
Heimdall MCP is an MCP server published on GitHub that lets an AI agent measure MCP latency and store traces for export through OpenTelemetry. Its repository has 11 stars and its last commit is from July 16, 2026, but it declares no licence.
What Heimdall MCP does
According to its repository: “Transparent MCP proxy that intercepts JSON-RPC messages, measures latency, stores traces in SQLite, PostgreSQL or MySQL, and exports OpenTelemetry spans.”
An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. Heimdall MCP is listed under Monitoring and observability, a category of 57 servers in the directory, where it ranks #36 by stars.
Topics declared by the repository: agent, audit, audit-trail, javascript, observability, opentelemetry.
Installing and connecting Heimdall MCP
No package or remote server is declared in the official MCP registry: you install it from source, following the repository README.
Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: TypeScript. Listed systems: macOS, Windows, Linux.
Security: what to check
An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.
Points found for Heimdall MCP:
- No licence: without a licence the code is not legally reusable, even if it is public. Avoid it in a company setting without the author's agreement.
Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.
Project activity and maintenance
Created on May 9, 2026, the enmanuelmag/heimdall-mcp repository has 11 stars and 0 forks, with 0 open issues. It has more stars than 28% of the servers in the directory. Last change 3 months ago.
Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
Verdict
Heimdall MCP is still a modest project: read its code and compare it with the alternatives before using it.
