At a glance

Launch and stop Java applications in Eclipse. An agent skill from gradusnikov/eclipse-chatgpt-plugin.

  • SKILL.md covers Tools, Examples and Notes
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Eclipse Run is an agent skill from gradusnikov/eclipse-chatgpt-plugin. Launch and stop Java applications in Eclipse. Run with program/VM arguments, capture stdout/stderr, or launch in background.

Its SKILL.md is about 780 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Java and Model Context Protocol. The repository describes itself as: Eclipse IDE as an MCP Server for AI Agents. The licence is MIT.

Example prompts

  • “/eclipse-run”

Requirements

  • Pre-approved tools (allowed-tools): mcp__eclipse-runner__runJavaApplication, mcp__eclipse-runner__launchConfiguration, mcp__eclipse-runner__listLaunchConfigurations, mcp__eclipse-runner__stopApplication, mcp__eclipse-runner__listActiveLaunches, mcp__eclipse-ide__getConsoleOutput

What it can do on your machine

Read from SKILL.md and the folder at commit b789344. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • mcp__eclipse-runner__runJavaApplication
    • mcp__eclipse-runner__launchConfiguration
    • mcp__eclipse-runner__listLaunchConfigurations
    • mcp__eclipse-runner__stopApplication
    • mcp__eclipse-runner__listActiveLaunches
    • mcp__eclipse-ide__getConsoleOutput

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    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

Eclipse Run loads about 780 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 263 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~780

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.

Run Java Applications in Eclipse

Launch Java applications using Eclipse's launch infrastructure. Applications run inside Eclipse with full classpath resolution.

Tools

  • runJavaApplication — Launch a Java app in run mode.

    • projectName — Eclipse project name
    • mainClass — Fully qualified main class (e.g., com.example.Main)
    • programArgs — Optional program arguments
    • vmArgs — Optional JVM arguments (e.g., -Xmx512m -Dfoo=bar)
    • timeout — Seconds to wait for completion. 0 = launch in background without waiting. Default: 30
  • launchConfiguration — Launch an existing saved launch configuration by name, exactly as it would run from the Run/Debug Configurations dialog. Reuses the configuration's full setup (classpath, VM args, environment variables, working directory, JRebel/agent settings) instead of building a throwaway one.

    • configurationName — Exact name of the saved configuration (use listLaunchConfigurations to find it)
    • mode — run or debug. Default: run
    • timeout — Seconds to wait for completion. 0 = background. Default: 0
  • listLaunchConfigurations — List saved launch configurations (name, type, and project/main class for Java apps). Use this to discover the exact name for launchConfiguration.

  • stopApplication — Terminate a running application by name/class substring match.

    • nameOrClass — Substring to match (case-insensitive) against launch name or main class
  • listActiveLaunches — Show all currently running/debugging sessions with status.

  • getConsoleOutput — Read output from Eclipse consoles (use after background launches).

Examples

Run and capture output:

runJavaApplication(projectName="myapp", mainClass="com.example.Main", timeout="30")

Run in background:

runJavaApplication(projectName="myapp", mainClass="com.example.Server", timeout="0")

Run with arguments:

runJavaApplication(projectName="myapp", mainClass="com.example.CLI", programArgs="--verbose input.txt", vmArgs="-Xmx1g")

Launch an existing saved configuration (preserves its env vars, VM args, JRebel, etc.):

listLaunchConfigurations()
launchConfiguration(configurationName="Run Snapshot App No Data Compass Local", mode="debug", timeout="0")

Stop a running app:

stopApplication(nameOrClass="Main")

Notes

  • When timeout > 0, the tool waits and returns stdout/stderr and exit code
  • When timeout = 0, the app runs in background — use getConsoleOutput to see output and stopApplication to terminate
  • Output is truncated at 5000 chars (stdout) / 2000 chars (stderr) to fit context

What does Eclipse Run need to run?

SKILL.md names no scripts, command-line tools or credentials: Eclipse Run is instructions for the agent only. Its frontmatter pre-approves these tools: mcp__eclipse-runner__runJavaApplication, mcp__eclipse-runner__launchConfiguration, mcp__eclipse-runner__listLaunchConfigurations, mcp__eclipse-runner__stopApplication, mcp__eclipse-runner__listActiveLaunches, mcp__eclipse-ide__getConsoleOutput.

Does Eclipse Run access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Eclipse Run safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Eclipse Run use?
