Highlights
Open for Collaboration
MCP Steroid is full open under Apache 2.0 with 84+ prompt resources, Docker integration tests for Claude, Codex, and Gemini, and DPAIA arena benchmarks. Contribute a scenario, run the evals, improve a skill: github.com/jonnyzzz/mcp-steroid.

A Drop-in Replacement for LSP
MCP Steroid now positions itself as a stateful, drop-in replacement for LSP in its server instructions. Agents see concise, exec_code-first guidance with a clear three-step flow: list_projects → fetch_resource → execute_code. The old skill guide routing table (which agents never read — 0 out of 69 arena runs) has been removed.
New Tool: steroid_fetch_resource
Agents can now load mcp-steroid:// skill guides directly from the tool list. The description maps task intent to the right resource:
- Running tests? →
mcp-steroid://prompt/test-skill - Debugging? →
mcp-steroid://prompt/debugger-skill - Any IDE task? →
mcp-steroid://prompt/skill
Maven Test Execution Fix
Fixed a critical bug where the ModalityStateMonitor killed Maven test execution prematurely. Maven’s runWithModalProgressBlocking creates a coroutine-based progress entity (JobProviderWithOwnerContext), not a UI dialog — the monitor now skips it. New Docker integration tests validate end-to-end Maven and Gradle test execution.
Plugin Verifier Compliance
Six internal IntelliJ API usages replaced with public alternatives — down from 29 to just 4 unavoidable internal references. This improves forward compatibility with future IntelliJ versions:

Improved Action Discovery
steroid_action_discovery now explains the discovery→exec_code workflow: call it first to find available quick-fixes, refactorings, and gutter actions, then invoke them via steroid_execute_code.
CI and Infrastructure
- GitHub Actions Node24 compliance across all workflows
- Pages workflow triggers on
