Description

Describe the Bug

I am attempting to enable the GitHub MCP (Model Context Protocol) integration. I have set the OC_CF_GITHUB_PAT environment variable, and the opencode debug config command confirms that the Authorization header is being constructed correctly.

However, when I actually attempt to run OpenCode and try to turn on the MCP, "nothing happens" (Failed). There is no error message thrown to the console; it appears to be a silent failure during the runtime initialization of the MCP, despite the configuration validator giving it a pass.

To Reproduce

  1. Set the environment variable in PowerShell: 
    $env:OC_CF_GITHUB_PAT = 'my_github_pat'
  2. Verify the environment variable is accessible to Node: 
    node -e "console.log('Bearer ' + process.env.OC_CF_GITHUB_PAT)"
# Output: Bearer my_github_pat
  3. Run the OpenCode debug configuration to verify internal recognition: 
    opencode debug config 2>&1 | Select-String -Pattern "Authorization"
# Output: "Authorization": "Bearer my_github_pat"
  4. Start OpenCode / Attempt to use GitHub context.

Expected Behavior

OpenCode should initialize the GitHub MCP, and I should be able to access GitHub context/repositories.

Actual Behavior

The tool starts, but the GitHub integration is not active. No authentication errors are logged, even though the configuration debugger shows the token is present.

Screenshots / Logs

Output from my verification steps showing the config is seemingly correct:

PS > $env:OC_CF_GITHUB_PAT = 'my_github_pat'
PS > node -e "console.log('Bearer ' + process.env.OC_CF_GITHUB_PAT)"
Bearer my_github_pat

PS > opencode debug config 2>&1 | Select-String -Pattern "Authorization"
        "Authorization": "Bearer my_github_pat"

Environment

  • OS: Windows 10
  • OpenCode Version: 1.1.21
  • Shell: PowerShell 7.x
  • Terminal: Warp

Additional Context

  • The PAT has valid scopes (Repo/Read).
  • Since opencode debug config sees the variable.
  • Works Hardcoded "Authorization": "Bearer my_github_pat"

Relevant parts of my opencode.jsonc
