Summary

  • server.json for the official MCP Registry: ai.sim/sim, one streamable HTTP remote at https://mcp.sim.ai/mcp, no packages or headers (OAuth is discovered from the 401). Publishing still needs a DNS TXT record on sim.ai and mcp-publisher publish
  • Claude Code plugin in plugins/sim with the root .claude-plugin/marketplace.json the plugin directory expects. The MCP server is declared inline in the manifest, so there is no .mcp.json and nothing loads for contributors working in this repo
  • README MCP section with Claude Code, Claude, and Codex setup
  • The MCP server info, server.json, and the plugin icon use the current Sim wordmark instead of the retired brandbook icon

Type of Change

  • Improvement

Testing

  • claude plugin validate --strict passes on plugins/sim and the repo root marketplace
  • server.json validates against the 2025-12-11 registry schema; a copy with a 101-character description and a bad remote type is rejected
  • Both icon URLs return 200 as image/png
  • check:file-names, biome

Checklist

  • Code follows project style guidelines
  • Self-reviewed my changes
  • Tests added/updated and passing (new tests pass the test-audit authoring gate)
  • No new warnings introduced
  • I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)
