## Supported AI Agents

Claude Code, Codex, Gemini, Cursor, and any other coding agent that supports the latest MCP via HTTP Streaming.

## Highlights

### Compilation Error Visibility Fix

**AI agents can now see full compilation error details.** Previously, when code failed to compile, agents like Claude Code only saw "Execution ID: eid_..." — the actual compiler error message (type mismatches, unresolved references, syntax errors) was invisible. This made it impossible for agents to diagnose and fix compilation failures.

The MCP tool result contained multiple separate text content items, with the execution ID as the first entry. Some MCP clients only render the first text item when `isError=true`, hiding all subsequent content including the compiler output.

Tool results now always merge all text into a single content block, ensuring the complete output — compiler errors, warnings, hints — is visible to every MCP client. ([#14](https://github.com/jonnyzzz/mcp-steroid/issues/14))

### Progress Reporting Fix

MCP progress notifications were silently discarded because `ExecuteCodeToolHandler` was not passing the progress reporter through to the execution engine. Agents using `_meta.progressToken` now receive real-time progress updates during code compilation and execution.

### Other Improvements

- **Cleaner tool output:** Removed duplicate "Execution ID:" line and "use it to report feedback" noise from tool responses.
- **EULA fix:** The plugin build and GitHub releases now correctly bundle the EULA instead of the Apache 2.0 license.
- **JetBrains Marketplace:** Plugin is now available on [plugins.jetbrains.com](https://plugins.jetbrains.com/plugin/30019-mcp-steroid).
