agent: mcp

When does this happen?

IF Package declares Node 18 support but a direct dependency requires Node >=20, causing engine incompatibility errors on Node 18.

How others solved it

THEN Ensure all direct dependencies are compatible with the declared engine range in package.json. If a dependency requires a newer Node version, either update the declared minimum Node version or find an alternative compatible dependency.

// package.json
{
  "engines": { "node": ">=18" },
  "dependencies": {
    "eventsource-parser": "^3.0.0" // this requires node >=20, causing conflict
  }
}
