error validating token - missing required scope 'read:org'

Not specified by the original author.

Short answer: the token itself lacks the read:org scope, and scopes cannot be added after creation. Mint a new token with the required scopes and give the tool that one instead. 1. Confirm what the current token actually carries. Run `curl -sI https://api.github.com/user -H "your auth header and read the X-OAuth-Scopes response header (redacted in logs; check it locally, never paste the token itself anywhere). Expected: read:org is absent from the list, which confirms the diagnosis. 2. Create a replacement classic personal access token under the GitHub account the tool should use, selecting at minimum read:org plus the scopes the tool validates for (for Copilot in VS Code that is typically repo and workflow as well, with gist and write:packages commonly also required). Expected: the new token's scope list includes every required entry. 3. Replace the token in the tool (for Copilot, sign out in VS Code and sign in with the new PAT where the extension asks for it), then retry. Expected: token validation passes with no missing-scope error. 4. If you use a fine-grained token or an OAuth app flow instead, the equivalent fix is at the source: fine-grained tokens need Organization permissions (Members: read-only) granted for the org, and OAuth apps must request the read:org scope in the authorize step so the user can grant it. Re-run the flow so a new token is issued with the scope. Root cause: GitHub encodes the granted scopes into the token at creation time. A tool that needs organization data validates the scope list up front and refuses to start, rather than failing later on individual API calls, which is why the error names the scope instead of a resource. When to use: a desktop tool, extension, or integration rejecting a hand-supplied GitHub token at setup with a missing-scope message. When NOT to use: a 403 on one specific API call with an otherwise working token is a per-resource permission or SSO authorization issue (organization SAML enforcement requires authorizing the token for that org, a separate step in token settings). Variant phrasings: "missing required scope read:org copilot", "error validating token read:org vscode", "github pat read:org scope required". Edge cases: tokens belonging to an organization with SAML SSO must also be authorized for that org after creation, or org calls fail even with the right scope. Never embed a PAT in a git remote URL in shared configs; it leaks the credential into shell history and logs.

Context: This error appears when a tool validates a GitHub personal access token before use, most often GitHub Copilot in VS Code being given a PAT for a different account, and finds the token was created without the read:org scope. OAuth scopes are fixed when a token is minted; they cannot be added to an existing token afterwards. Copilot's token validation also typically expects repo and workflow alongside read:org, so a token created with only one or two of them fails this check.
