agentgo-mcp

The MCP server for AgentGo, the browser your AI agent drives. MIT licensed.

AgentGo is a real Chromium browser for Windows 11, built for agents. This repository is the part your agent talks to: the MCP server, the local control protocol it speaks to the browser, the command registry and the policy types. The browser itself lives in the main repository.

• Compact pages. browser_open and browser_read return a short outline: headings plus interactive elements as [ref] role "name".
• Only what changed. browser_act and browser_batch use real mouse and keyboard input, wait for the page to settle, and reply with the diff, not the whole page again.
• The human stays in charge. Payments and final submissions come back as approval.required; the agent calls browser_wait_human and you approve in the browser.
• Accounts without tokens. browser_account calls the APIs of accounts you linked, without the agent ever holding a token.
• Built for single-page apps. Repeated buttons say which row they belong to, a reference that a re-render moved to another item heals or fails loudly instead of clicking the wrong row, browser_act {action: "scroll", until} scrolls a long or virtual list in one call, browser_wait takes named conditions (enabled, gone, text), and any action can say what must happen (expect).
• GoMini. When the on-device model is on, browser_delegate hands it routine steps.

On 24 BrowserGym MiniWoB++ tasks with the same model, AgentGo solved 22, browser-use 19 and Playwright MCP 18 (method and results). With 0.1.6, on 37 tasks including 14 single-page apps and all four browsers running at the same time: AgentGo with GoMini v6 solved 37, AgentGo 37, browser-use 35 and Playwright MCP 31, with AgentGo using 95-114k input tokens per task against 227-306k (0.1.6 results).

Tools

browser_open, browser_read, browser_act, browser_batch, browser_wait, browser_tabs, browser_screenshot, browser_wait_human, browser_guide, browser_account, browser_call, plus browser_delegate when GoMini is on.

Use it

Install AgentGo from the latest release. Its installer connects Claude Code, Codex or Droid for you, using agentgo mcp.

Claude Code plugin: the server and the agent guide in one step.

/plugin install agentgo --marketplace Moha2005269/agentgo-mcp

Claude Desktop: open agentgo-mcp-0.1.6.mcpb to install it as an extension.

MCP Registry: listed as io.github.Moha2005269/agentgo.

To run this server from source instead:

cargo build --release -p agentgo-mcp --bin agentgo-mcp

Then point your MCP client at target/release/agentgo-mcp. It attaches to the newest running AgentGo, or starts agentgo from PATH (set AGENTGO_EXE to use another path).

{ "mcpServers": { "agentgo": { "command": "C:\\path\\to\\agentgo-mcp.exe" } } }

Offline mode

agentgo-mcp-offline builds on any OS and answers initialize and tools/list with the real tool list, with no browser behind it. Tool calls explain where to get AgentGo. It exists so MCP directories can check the server; the Dockerfile builds it.

Data

AgentGo is a browser, so the pages your agent opens and the forms it submits go to those websites, as they would from any browser. Nothing goes to us: no telemetry, no accounts, and your profile (history, cookies, saved sign-ins) stays on your computer. Payments and final submissions wait for your approval. See PRIVACY.md and the browser's network calls.

Layout

Tests: cargo test --workspace.

This repository mirrors the same crates in the main AgentGo repository, where they are developed.
