fix/opencode mcp gitnexus timeout

[juampymdd]

PR Description

This PR updates the README to fix the MCP configuration for OpenCode, which was not working with the previous setup.

I validated the behavior against OpenCode's current MCP documentation. For local MCP servers, OpenCode defines command as an array containing both the executable and its arguments, for example:

{
  "mcp": {
    "my-local-mcp-server": {
      "type": "local",
      "command": ["npx", "-y", "my-mcp-command"]
    }
  }
}

There is no documented support for a separate args field in this context.

Because of that, using:

{
  "command": "npx",
  "args": ["-y", "gitnexus@latest", "mcp"]
}

does not match the documented configuration format, and in my case OpenCode rejected it.

The working configuration aligned with the docs is:

{
  "mcp": {
    "gitnexus": {
      "type": "local",
      "command": ["gitnexus", "mcp"]
    }
  }
}

@magyargergo this is not a big fix but can you look at it and make sure that it is not redundant, I know the npm install -g gitnexus is already on the readme but it is in an inconvenient place

[magyargergo]

This works me fine. Please reopen it if still an issue.

P.S Thanks @zander-raycraft

Thanks for checking this.

    }
  }
}

So the intention of my PR was to make the README consistent with OpenCode’s documented MCP configuration and avoid confusion for users.

This is great, reopen it and I can finalize and merge it

[juampymdd]

I’m not seeing the “Reopen” option on my side, so I don’t think I have permission to reopen the PR.

The issue is still valid though: OpenCode does not accept args in the MCP configuration, so the current README example does not work as expected.

If you can reopen it, I can update the PR with more details or adjustments.

Summary

This PR makes a 2-line documentation fix to the OpenCode MCP configuration in README.md. The change is minimal, correct, and low-risk.

---

What Changed (README.md)

Before (broken):

{
  "mcp": {
    "gitnexus": {
      "type": "local",
      "command": "npx",
      "args": ["-y", "gitnexus@latest", "mcp"]
    }
  }
}

After (correct):

{
  "mcp": {
    "gitnexus": {
      "type": "local",
      "command": ["gitnexus", "mcp"]
    }
  }
}

---

Technical Correctness ✅

The fix is correct. OpenCode's MCP local server spec defines command as an array [executable, ...args] — there is no separate args field. The original config used a Cursor/Claude Code format that OpenCode does not support, causing silent rejection. This has been confirmed working by both the PR author and @swelborn.

---

Minor Concern — Global Install Dependency ⚠️

The proposed config uses ["gitnexus", "mcp"], which requires gitnexus to be globally installed (npm install -g gitnexus). All other editor configs in the README use npx to avoid this requirement:

Editor	Requires global install?
Claude Code	No (npx -y gitnexus@latest mcp)
Cursor	No (npx + args)
Codex	No (npx + args)
OpenCode (this PR)	Yes (gitnexus binary)

An alternative that avoids the global install requirement would be:

"command": ["npx", "-y", "gitnexus@latest", "mcp"]

However, the PR author validated this against OpenCode's documentation and their real environment, and the existing README already mentions npm install -g gitnexus in the Quick Start section. The current fix is a clear improvement over the broken format. @zander-raycraft already flagged this concern and the consensus was to merge as-is.

Risk Assessment

Factor	Assessment
Scope	Documentation only — zero code impact
Correctness	Validated against OpenCode docs + real usage
Community confirmation	2+ users confirmed it works
Regression risk	None — other editor configs are untouched

---

Recommendation: ✅ MERGE

This is a clear, correct documentation fix. The change resolves a real user-facing issue (OpenCode rejecting the config), has been validated by multiple users, and touches only 2 lines in the README with no risk of regression. The minor inconsistency around global install is a pre-existing documentation concern and not introduced by this PR.
