Yes, this is on purpose. Pod is built for agents, so the default page is plain HTML.
Human? View the normal website.
Agent? You probably prefer /mcp/azure-devops-ado/issues.md or /mcp/azure-devops-ado/issues.json, or Pod over MCP.

Reported issues for Azure DevOps (ADO)

[REMOTE] AADSTS70007: unsupported mode 'query' — default interactive auth fails before any browser prompt (local stdio server, Windows 11 / Node 24)

Description

Summary

With the default interactive authentication method, every tool call fails at token acquisition with:

AADSTS70007: The application requested an unsupported mode 'query' when requesting a token.
Trace ID: <redacted>  Correlation ID: <redacted>

No browser window ever opens — the failure happens roughly 4 seconds after start, before any sign-in prompt appears. The MCP server process itself starts and completes the protocol handshake normally, and the client h

Allow Interactive Browser Authorization for Machines without Azure CLI

Hi!

I would like to adapt the auth logic to fallback to interactive browser credentials if the Azure CLI is not present on the client machine.

This caters to users working in protected environments who have restricted access to install things on their machines.

Is this something that'll help with the project's vision?

Thanks!

Install doesn't work anymore

I had previously installed the MCP in my global user settings, so that I didn't need to setup it up per repo. Something changed (don't know what) the MCP was unloaded, and was no longer in my settings.json. Now when I click on the quick install link, it pops this up in VSCode

[REMOTE] Emit per-tool readOnlyHint annotations so read-only MCP clients (GitHub Copilot PR review) don't filter out every tool

Summary

The local MCP server (@azure-devops/mcp over stdio) registers all tools without MCP annotations, including annotations.readOnlyHint.

As a result, MCP clients that enforce a read-only tool policy treat every Azure DevOps tool as potentially state-changing and filter them all out, even when a tool only performs read operations. In GitHub Copilot PR review, this shows up as:

no allowed tools after filtering

According to the MCP specification, readOnlyHint is optional, but when it

Work item artifact links allow references to missing Azure DevOps resources

The work item link tools can add artifact relations for non-existent pull requests, branches, commits, or builds:

Azure DevOps stores the artifact URI without validating that the target exists, leaving a dangling relation.

Pull request vote reports success when the pull request does not exist

repo_pull_request_write with action: "vote" can report success for a non-existent pull request.

The current flow treats a missing reviewer as valid and does not independently confirm that the target pull request exists or that the vote was applied.

Expected behavior: validate the pull request in the requested project and repository before voting, and do not report success without a confirmed update.

Would you accept a focused PR with missing-PR and successful-vote tests?

As a result, a project outside the first page is missed:

This can return an empty array, while the same filter with a larger top finds the project.

Add tool to list pull request policy evaluations

Summary

No tool reports why a pull request is blocked. repo_pull_request returns mergeStatus, votes and completionOptions, but never the policy results, and the statuses API does not cover branch policies. #843 raised this and was closed as completed without a tool shipping, same for #1276.

The policy evaluations API does cover them, and it is already reachable through getPolicyApi() in the official Node API. It also answers the original ask in #843: the context of a build evaluati

add_child work items: ReproSteps is written unconditionally, populating non-Bug types (Task/User Story/Feature) with a duplicate, stale description

Summary

In src/tools/work-items.ts, the add_child action unconditionally writes the item's description into both System.Description and Microsoft.VSTS.TCM.ReproSteps for every child work item, regardless of work item type.

Microsoft.VSTS.TCM.ReproSteps ("Repro Steps") only exists on the Bug work item type in the Agile/Scrum process templates. Writing it to Tasks, User Stories, Features, etc. populates a field those types don't semantically own.
