What it does

Ide Diagnostics MCP is an agent skill from JetBrains/intellij-community, published by the product's own GitHub organization. Inspect a running IntelliJ IDE for freezes or blocked threads via MCP.

Its SKILL.md is about 750 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol and JetBrains IDEs. The repository describes itself as: IntelliJ IDEA & IntelliJ Platform.

When your agent uses it

  • Tasks that involve MCP servers

Example prompts

  • “/ide-diagnostics-mcp”

What it can do on your machine

Read from SKILL.md and the folder at commit cbaf50b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are json and bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ide Diagnostics MCP loads about 749 tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 338 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~23
When it runs · the whole SKILL.md, loaded when a task matches
~749

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 338 words (~749 tokens).

“Use the get_ide_diagnostics MCP tool to answer "what is this IDE doing right now?" from inside a running IntelliJ process.”
