MCP Tool Discovery

This server registers over 440 snow_* tools across 80 domains and lists none of them. A fresh tool list holds two meta-tools; everything else is behind tool_search. This guide is about getting from "there is probably a tool for this" to a call that actually runs.

No exact total is quoted here, because there are two of them and they disagree: packages/servicenow-mcp/tools.json is what the docs site publishes, the registry is what the running server can dispatch, and nine published tools are missing from the registry (see "Nine tools you can find in the docs but not on the server").

Cold start: two tools

A fresh tools/list on the stdio transport returns exactly this, no matter how many tools exist:

tool_search
tool_execute
