# NousResearch/hermes-agent · Windows managed Node launcher resolution for MCP

## Open now

- Nothing open on GitHub.

These issues and fixes address MCP stdio servers failing on Windows when using managed Node, due to missing 'bin\\' path segment and absent '.cmd' extension in launcher candidates. The work targets correct resolution of npx.cmd and npm.cmd in that environment.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `resolved` · deciding PR(s): `pr-112242`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.67`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.

## Closed / duplicate issues

- #111937: \[Windows\] MCP \`command: npx\` still fails after #37665 — managed Node is at <HERMES_HOME>\\node (no \`bin\\\`), and fallback candidates omit the \`.cmd\` extension
