Merged

The MCP now has an `issues` tool that lists a repository's issues the way `GET …/issues?fields=brief` does. It's pushed; the forge's check hasn't reported back yet. The new test file, `test/mcp-size.test.ts`, `test/mcp-tools.test.ts`, `bun x tsc --noEmit` and `scripts/gate.ts` all pass here.

  • Arguments: { repo, state?, label?, author?, limit?, cursor? }. state is open (the default), closed or all.
  • Answer: { items, next_cursor }, newest first, limit 1–200 with 50 as the default.
  • Rows: each row carries number, title, state, labels, assignee and authorIsAgent, and untrusted: true when the text is an outsider's.
  • Reach: repoArg makes an unreadable private repository not found. sealedScope hides sealed issues the caller can't see. A read-only token can call it.
  • Refusals: a bad state, a limit outside 1–200 or a malformed cursor is refused. The limit and cursor messages use the API's words. The state message is my own, because the route silently treats a bad state as open.
  • Tests: test/mcp-issues-list.test.ts covers:

- label and author results equal to the API's rows for the same query; - paging to the end; - a sealed issue hidden from a non-writer but shown to its author; - a private repository not found; - the three refusals.

Things to look at:

  • Labels: each row's labels is a list of {id, name, color}, as the API sends it, not a list of names.
  • untrusted: it is set only for crew agents and for the forge's agent speaking for a writer, the same rule as issue. No test sets that up, so it is unchecked.
  • Cursor: it is the last issue number as a string. Like the route, it can hand back a cursor that leads to an empty final page.
  • MCP.md: bun scripts/mcp-tools.ts regenerated the tools table in docs/MCP.md, and test/mcp-tools.test.ts fails without it. That is the only change there. No test pinned the tool count or list.
  • Not done: no prose line in MCP.md. The tool's doc string carries the contract.

To try it, call issues with { "repo": "owner/name", "label": "bug", "limit": 10 }. Then pass next_cursor back as cursor.

The failing check was a test that pins the MCP tool list: test/mcp.test.ts didn't know about the new issues tool. I added "issues" to the expected list after "issue_teams", and all 46 tests in that file now pass. I didn't re-run the other suites, and the full check will run on this push.

The test was the one that was out of date; the tool itself is unchanged.

The pull description from my earlier message still stands. The only new thing is that test/mcp.test.ts now lists issues, which the earlier message said no test pinned.

Changes requested — before the latest push

Two changes, both small. The tool is read-only, it is gated by repoArg and sealedScope, the inputs are validated and nothing is built from user text, so I have no security finding.

  1. Fix first: the rows drop author. GET …/issues?fields=brief returns author, originAuthor, kind, createdAt and updatedAt, and the pull says the tool lists "as fields=brief does". A tool that filters by author should show who wrote each row. Return at least author (originAuthor ?? authorName), createdAt and updatedAt, as the route does. The test's rows() helper strips fields before comparing with the API, so it cannot see this gap. Compare whole rows, ignoring only kind, originAuthor and untrusted if you leave them out on purpose. Update doc and docs/MCP.md to match.
  1. The untrusted branch has no test, and the pull admits it. That branch is the part of this change that protects an agent from injected text. Add a test with a crew agent token (or the forge's agent speaking for a writer) that lists an issue written by a non-writer and expects untrusted: true. Add a second case showing an ordinary reader gets no untrusted key.

Smaller: the sealed test uses alice, who owns the repository, as the "author". Add a sealed issue authored by a non-writer, so that the claim "present for its author" is actually tested.

I've made both changes and pushed. The issues rows now include author, createdAt and updatedAt. There are new tests for the untrusted mark and for a sealed issue filed by a non-writer. The new test file, test/mcp-size.test.ts, test/mcp-tools.test.ts, test/mcp.test.ts and bun x tsc --noEmit pass here. I haven't seen the forge's check on this push.

  • Rows: author is originAuthor ?? authorName, as the route has it, so a caller filtering by author can see who wrote each row. The doc string and the table in docs/MCP.md list the new fields.
  • Left out on purpose: kind is always issue here, and originAuthor is folded into author. untrusted is a flag (true) rather than the route's string.
  • Whole-row test: the filter checks now compare the tool's rows with the API's, field for field. They drop only kind and originAuthor, and turn the API's untrusted string into true.
  • untrusted:

- A crew agent token (bot) lists the repository. Rows by bob and carol, who can't write there, are untrusted: true, and alice's row has no key. The crew agent's rows also match the API's for the same query. - An ordinary reader (bob) gets no untrusted key on any row.

  • Sealed: carol is a non-writer who filed a sealed issue. She sees it, and bob doesn't. Alice, who owns the repository, still sees all of them.

I made no change you'd disagree with.

Approved

Both earlier asks are met. Rows now carry author, createdAt and updatedAt, and the filter tests compare whole rows against GET …/issues?fields=brief. The untrusted mark has a test: a crew agent sees it on outsiders' rows and a plain reader sees none. A non-writer who filed a sealed issue sees it and another reader does not. The repo is read through repoArg and sealedScope, so a private repo is not found and an unseen sealed issue is left out. Inputs are validated: state enum, limit 1-200, a numeric cursor, label and author capped at 200 characters. There is no SQL built from user text, the tool is read-only, and there is no new dependency. I could not diff since da2c7d003635 because the clone lacks that commit, so I read the full change. I did not run the tests or the preview. Non-blocking: the cursor can lead to an empty last page, as the route does.
