github mcp tool field issues

[davidkgp]

Bug Description

I am trying to built an automation with github mcp tool, when the mcp tool is rendered, add_comment_to_pending_review , it seems I cannot pass in the numerical fields(pullnumber, line nr, startline) from the previous step. Is it because the data type is a numerical, this kind of renders the pipeline unusable since the numbers(line, startline) can vary based on cases, but since i cannot connect the previous stage to this , it creates an issue. Please provide some guidance.

Reproduction

• install Github MCP Tool
• In the MCP tool select add_comment_to_pending_review

{
  "mcp": {
    "servers": {
      "github": {
        "command": "/path/to/github-mcp-server",
        "args": ["stdio"],
        "env": {
          "GITHUB_PERSONAL_ACCESS_TOKEN": "<YOUR_TOKEN>"
        }
      }
    }
  }
}

• now try to connect to the numerical fields(pullnumber, line nr, startline) from the previous step(e.g. chat input)

Expected behavior

all fields of mcp tool should be allowed to be connected
