What it does
Idea MCP is an agent skill from dtprj/dongting. IntelliJ IDEA MCP for Java code analysis, testing, refactoring, and project navigation. Use when: (1) Checking Java compilation errors (getfileproblems is more accurate than LSP for multi-module Maven), (2) Performing rename refactoring across the codebase, (3) Searching code or finding files in the project. Requires IDEA to be running with MCP plugin connected.
Its SKILL.md is about 700 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 Development, covering Refactoring and MCP servers. It works with Model Context Protocol, Java and JetBrains IDEs. The repository describes itself as: Java raft/config/mq/rpc engine, zero dependencies, 10X faster. The licence is Apache-2.0.
When your agent uses it
- Checking Java compilation errors (getfileproblems is more accurate than LSP for multi-module Maven)
- Performing rename refactoring across the codebase
- Finding files in the project
Example prompts
- “/idea-mcp”
What it can do on your machine
Read from SKILL.md and the folder at commit 0d366e7. 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
Shell commands in SKILL.md call:
mvn
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
Idea MCP loads about 698 tokens when it runs. Until then it costs about 94 tokens; SKILL.md has 268 words of instructions outside code blocks.
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.

Path Rules (Most Common Error Source)
| Parameter | Path Type | Example |
|---|---|---|
projectPath | ABSOLUTE | /Users/huangli/dt/dongting |
filePath, pathInProject, directoryPath, contextPath | RELATIVE | server/src/main/java/... |
Getting this wrong is the #1 cause of "file not found" errors.
Gotchas and Tips
Two Search API Families
IDEA MCP has two sets of search tools that return different formats. Pick the right one:
search_in_files_by_text/search_in_files_by_regex— Returns matched lines with||highlight||markers. Good for quick "where is this string used" lookups. SupportsfileMaskfilter.search_text/search_regex/search_file/search_symbol— Returns structured results with exact coordinates (line, column, byte offsets). Supportspathsglob filters and!excludes. Use this when you need precise locations for further operations.search_symbolis especially powerful — semantic symbol lookup (classes, methods, fields) returning full code snippets.
execute_terminal_command Does Not Use Shell by Default
Without executeInShell: true, shell features like $() expansion, pipes, and wildcards won't work. For most shell commands, prefer the Bash tool directly.
rename_refactoring Takes Symbol Name, Not Position
Parameters are symbolName (the exact identifier string) and newName, not file path + line/column. This is different from LSP-based rename.
build_project for Single-File Compilation
build_project with filesToRebuild parameter compiles specific files much faster than running mvn compile. Useful for quick verification after edits.
get_file_problems vs LSP Diagnostics
For multi-module Maven projects, get_file_problems is significantly more accurate than LSP lsp_diagnostics. Prefer it for Java error checking.
High-Risk Operations
rename_refactoring&replace_text_in_file— Modify code globally, verify withget_file_problemsafter usereformat_file— Modifies formatting without confirmation
Troubleshooting
| Issue | Solution |
|---|---|
| Connection refused | Verify IDEA running with MCP plugin |
| Request timed out | Accept permission dialog in IDEA |
| File not found | Check absolute vs relative path (see Path Rules above) |
