v0.3.0

Experimental Rust MCP bridge for the official Google Antigravity CLI.

A submission now requires only instructions. The task text goes to the CLI unchanged, and ag_result.text returns the original answer: plain text, Markdown, code or JSON. Version 0.3 removes forced report fields, semantic evidence checks, task categories and --json-schema.

• Default host execution with automatic current-user CLI permissions and no isolation.
• No default task deadline or result expiry. Accepted jobs survive client disconnection.
• Eight MCP tools cover submission, progress, results, cancellation, discovery, quota control and result disposal.
• Full private audit capture by default, rotation without deletion, and an explicit complete off switch.
• Optional root, native model slug and arbitrary metadata label. An absent or empty allowedRoots list disables the starting-directory allowlist.
• Shared FIFO scheduling and retry-key deduplication, with no automatic task replay.
• Optional Linux isolation and patch delivery; macOS and Windows explicitly reject isolated requests.
• Six native release archives for Linux, macOS and Windows on x86-64 and ARM64.
• An optional dependency-free npx launcher, available through the versioned GitHub package tarball.

The tag CI passed all six native jobs and published this release. Download the matching archive and verify it against SHA256SUMS. Install and authenticate the official agy separately.

Actual installed Codex and Claude Code sessions on Linux and Windows submitted and retrieved Gemini 3.8 Flash High jobs. Codex exited before completion; Claude Code collected the retained answer and independently checked the output file. Captured task text and returned answers matched the native CLI exactly, with no required JSON report. See the verification record for measured outcomes and unverified workflows.

The README documents the public GitHub-tarball npx command. The unqualified npm registry package remains unpublished. The launcher verifies and caches native bytes and forwards MCP stdio.

For existing configurations, set timeoutSeconds and retentionSeconds to zero for unlimited task duration and result retention. Set allowedRoots to [] to remove an old starting-directory allowlist. Windows retains configurable desktop fallback. Older answers and audit logs remain readable; historical terminal states are preserved without replay.

The source, documentation and dependency notices are English. This community project has no Google affiliation. The RPD describes the complete interface and operation boundaries.

v0.2.1

Experimental Rust MCP worker for the official Google Antigravity CLI.

• Eight tools for background delegation, status, reports, cancellation, discovery, quota control and result disposal.
• Default host execution with full current-user permissions and automatic CLI approval.
• No default task deadline; jobs survive client disconnects and results are shared across fresh client sessions.
• Idempotent retries, shared FIFO scheduling and quota pause, with explicit cancellation and no automatic replay.
• Optional Linux workspace isolation, paged patches and read-only analysis with useful native tools and writable helper caches.
• Native CI builds and tests for Linux, macOS and Windows on x86-64 and ARM64.
• Optional dependency-free npx launcher, published as a GitHub release tarball.
• Full private audit logs by default, rotation without automatic deletion, and an explicit complete off switch.
• Autonomous agent execution without added behavioral instructions; live Codex and Claude Code checks with independently inspected results and traces.

Download the archive matching your operating system and architecture, and verify it against SHA256SUMS. Archives include the executable, MIT license, dependency notices and English documentation. Install and authenticate the official agy separately, then configure its executable path and model profiles.

The README documents npx usage with the included npm tarball URL. That entry point does not need an npm registry publication; the unqualified npm package name is not yet published. The launcher verifies and caches the native executable and passes MCP stdio through unchanged.

Isolation requires Linux. Windows and macOS support host mode and explicitly reject isolation requests. See the README, complete RPD and verification record for permission boundaries and checks that remain unverified. This project has no Google affiliation.

Upgrading from 0.1: remove the obsolete researchDomains field and set timeoutSeconds and retentionSeconds to zero in existing configuration files to adopt unlimited task duration and result retention. Results have bounded capacity; ag_forget explicitly frees terminal-result slots while preserving logs and deduplication. Windows hosts must permit Job Object breakaway; unsupported launch contexts fail explicitly.

Verified integration

All six native v0.1.2 CI jobs and the release publisher passed. The public GitHub-tarball npx command passed a cold download, cached startup and a real MCP capability call on Linux x86-64. Fresh Codex 0.160.0 and Claude Code 2.1.285 sessions also called the server successfully using global registrations generated by a local CC Switch 3.20.4 build.

The client guide includes CC Switch setup and client approvals. The verification record records actual tasks, audit retention and remaining model/platform limits. The complete RPD describes the product contract.
