What is the Heimdall MCP Server?

Transparent MCP proxy with OpenTelemetry tracing and configurable storage

What the server does

Transparent proxy for any MCP server. Intercepts all JSON-RPC messages, measures latency, stores traces in a configurable database, and enforces per-server allow/deny policies — without touching the original server.

More MCP options

Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
