google-jules-mcp-server MCP Server

Model Context Protocol server for Google's Jules AI coding agent

Publisher claimed. No tool list reported, and Pod has not connected to this server.

Status

Pod has not dialled google-jules-mcp-server yet, so everything on this page is what its publisher reported rather than what we observed. Registries describe servers; they do not connect to them. Until a check runs, treat the tool list below as a claim.

Connect

Published as google-jules-mcp-server on npm. Runs locally.

Known issues

31 problems reported by people outside the maintainer team. Issues filed by the project's own owners, members and collaborators are excluded — those are release checklists and internal refactors, not things that will go wrong for you. Showing 12.

Session change-set outputs are discarded: a session whose result is a patch has no way to surface it

What's the problem?

SessionOutputSchema (src/resources/sessions/schemas.ts:34) models a single field:

export const SessionOutputSchema = z.object({
  pullRequest: PullRequestSchema.optional(),
});

Real sessions return more than that. Session 18290074838581230171 came back with outputs as [changeSet, pullRequest], where the change set carried the complete diff:

outputs[0].changeSet.gitPatch.unidiffPatch  — the full unified diff
outputs[0].changeSet.gitPatch.baseCom

### Trim char-budget constants in activities/format.ts

**What's the problem?**
`src/resources/activities/format.ts:25-31` defines 6 char-budget constants (`SUMMARY_CHAR_BUDGET`, `LIST_ITEM_CHAR_BUDGET`, `LIST_PAGE_CHAR_BUDGET`, `DETAIL_CHAR_BUDGET`, `CHANGE_SET_DIFF_CHAR_BUDGET`, `LIST_ITEM_SLACK`). `LIST_ITEM_SLACK = 150` is self-described over-tuning in its own comment ("Below this the recovery hint costs more than the cut saves").

**Proposed solution**
Collapse to the 2-3 constants that actually gate a different render path. Est. -3 lines, fewer

### Create AGENTS.md

**What's the problem?**
I want to make agent-driven development better by providing context to the AI agents. As I started using Jules for development of this MCP Server, Jules can work better when AGENTS.md file is present.

**Proposed solution**
- Create an AGENTS.md file covering the current project in depth, following best practices for creating AGENTS.md.

**Alternatives considered**
No AGENTS.md exists.

**Sample AGENTS.md for this project**

```bash
# AGENTS.md

## Project Overview
- **Co

### Minimum Codecov coverage threshold

**What's the problem?**
Every time when a new PR is created, if the code coverage drops bellow previous value, Codecov will will fail and the PR will cannot be merged.

**Proposed solution**
Setup a minimum code coverage threshold of 90% with a thresholds of 1%. This is for the entire project.

```yaml
coverage:
  status:
    project:
      default:
        target: 90%      # Minimum expected total coverage percentage
        threshold: 1%    # Allowed drop leeway percentage before failing

jules_get_session_output reports "no pull request was created" when the PR is not first in outputs[]

Describe the bug

session.outputs is a list that can hold more than one entry, and the pull request is not reliably the first one. All three session formatters read index 0 and nothing else:

src/resources/sessions/format.ts:12 — formatSessionList
src/resources/sessions/format.ts:81 — formatSessionStatus
src/resources/sessions/format.ts:112 — formatSessionOutput

When a session emits a change set as well as a PR, index 0 is the change set, so the PR at index 1 is never se

Collapse 7 error subclasses into one parametrized JulesApiError

What's the problem? 5 of the 7 classes in src/core/errors.ts (JulesAuthError, JulesNotFoundError, JulesServerError, JulesClientError, JulesNetworkError) are byte-identical: extends JulesApiError { constructor(m){ super; this.name="…"; } } (5-48). Only JulesRateLimitError (adds retryAfterMs?) and JulesResponseValidationError (adds path, zodError) carry extra data.

Proposed solution One `class JulesApiError extends Error { kind; status?; retryAfterMs?; path?; zodEr
