Hosting

Local process; optional self-hosted HTTP service

Transport

stdio by default; Streamable HTTP when explicitly configured

Endpoint

Local process; no hosted endpoint documented

Authentication

No MCP login; target Prometheus authentication/TLS is configured through documented HTTP client configuration as needed.

Requirements

• Prometheus or compatible backend reachable over HTTP
• Release binary for the local OS/architecture, or documented container deployment
• MCP-compatible client

Setup steps

1. Download the Prometheus MCP release binary matching the host OS/architecture.
2. Configure the process with the target address using --prometheus.url <PROMETHEUS_URL> or PROMETHEUS_MCP_SERVER_PROMETHEUS_URL. Do not store credentials in the catalog or prompt.
3. Use the binary as a local stdio MCP server; the repository documents HTTP mode separately.
4. Restart the client and inspect tools. Test with a harmless read-only query against a non-sensitive metric.

The current repository reference lists 27 default tools. Three TSDB Admin tools are separately gated by --dangerous.enable-tsdb-admin-tools and are excluded from this default inventory.

• Requires a reachable Prometheus-compatible backend and can expose the data available to the configured identity.
• Tool surface is configurable; TSDB administration tools require an additional flag.
• This is a local/self-hosted integration; no vendor-hosted endpoint or OAuth service is documented.
