Template for skills that integrate with an MCP server. Demonstrates the reference file pattern: Claude reads a domain-specific MCP cheatsheet before making any tool calls, reducing query failures caused by server-specific gotchas. Fork this skill and replace the Sentry example with your target MCP.
Passed 16 of 21 test cases with the skill, and 7 of 21 without it.

I want to create a new MCP reference template for Datadog based on the repository structure. What exact shell command should I run to copy the template directory?
| Checked | Without skill | With skill |
|---|---|---|
| Specifies cp -r examples/skills/mcp-integration-reference examples/skills/<your-skill>/ as the copy command. | Missed | Passed |
The instructions your model reads when the skill loads.
This is a template skill. It shows how to structure a skill that wraps an MCP server. Replace
sentrywith your MCP server name and adapt the reference file atreferences/sentry-mcp.md.
When a skill calls an MCP server without prior context, Claude guesses at the query syntax. This works for simple calls but breaks on anything with non-obvious behavior: pagination quirks, required parameter combinations, rate limits, or subtle format restrictions.
The fix: a references/<mcp-name>.md file that captures all the gotchas. The skill reads this file before making any MCP call. Zero guessing.
Three types of content go in the reference file:
Before doing anything else, read the full MCP reference:
Read: references/sentry-mcp.md
This file contains query syntax, known gotchas, and working examples for the Sentry MCP. Do not skip this step.
