Goose is Block's open-source local-first AI agent, built with native Model Context Protocol (MCP) support from the ground up. Unlike cloud-based agent platforms, Goose runs entirely on the developer's machine — connecting to local MCP servers, reading files, running shell commands, and integrating with local services without sending data to third-party infrastructure. The agent supports multiple LLM backends (Anthropic, OpenAI, local Ollama models) and exposes a plugin-style architecture where capabilities are added as MCP servers. This means any developer can extend Goose with custom tools — a database connector, a local calendar integration, a custom code execution environment — without modifying the core agent. The design reflects Block's privacy-first engineering culture. Goose has been growing steadily in the developer community, particularly among engineers at companies with strict data security requirements who want agent capabilities without cloud data exposure. The local-first + MCP-native combination is genuinely differentiated — most agent platforms either require cloud APIs or bolt MCP on as an afterthought rather than building around it.

Web agents from OpenAI, Google, and Anthropic all cheat a little — they read the DOM or accessibility tree, getting structured page data that no human ever sees. MolmoWeb from the Allen Institute for AI (Ai2) doesn't. It navigates the web using only screenshots, the same visual interface a person uses: looking at the rendered page and deciding where to click, what to type, and when to scroll. The 8B model achieves 78.2% on WebVoyager (94.7% with multiple rollouts) — better than GPT-4o-based agents that have access to structured DOM data. The project's ambition is to be the OLMo of web agents: everything open. Weights (Apache 2.0), training data (36,000 human trajectories plus 108,000 synthetic ones — the largest public human web interaction dataset released), evaluation tools, and the full training pipeline. The 4B and 8B versions are self-hostable via FastAPI, Modal, or locally, and there's a public demo at molmoweb.allen.ai. Model architecture: Molmo 2 multimodal (Qwen3 backbone + SigLIP2 vision encoder). The gap to proprietary frontier systems (OpenAI CUA at 87%) is real, and Ai2's organizational stability is a legitimate concern after key researcher departures. But for researchers, the dataset alone is historically significant — and for builders who need a reproducible, auditable web automation baseline they can actually run and modify, MolmoWeb is the first genuinely credible open option.
Reviewer scorecard
“The MCP-native architecture is the right bet for 2026. Instead of each agent building its own tool integration layer, the ecosystem converges on MCP servers as the universal extension mechanism. Goose being built around this from day one means it ages better than competitors who bolted MCP on later.”
“As an open-source baseline for web automation research, this is immediately useful — the 36K human trajectory dataset alone is worth the star. For production web agent applications you'll still hit reliability issues with complex flows, but for proof-of-concepts, QA automation, and research prototypes where you need an auditable system you can actually inspect and fine-tune, this is a huge step forward.”
“Running locally is a privacy win but also means you're responsible for setup, updates, and debugging when things break. For teams without a dedicated platform engineer, the operational overhead of a local-first agent is real. Also, Goose's cloud connectivity features (for collaboration) create the same privacy exposure it's trying to avoid.”
“78% on WebVoyager sounds impressive until you realize OpenAI CUA hits 87% and handles things MolmoWeb explicitly can't: login flows, financial transactions, and drag-and-drop. Cascading failures from early mistakes are a real production risk, and the demo is restricted to a whitelist of sites. Key Ai2 researchers have left for Microsoft, which raises honest questions about whether this gets the maintenance it needs to stay competitive.”
“Block building a local-first agent is a quiet but important data point: large companies are hedging against cloud AI dependency. As MCP becomes the standard protocol for AI tool connectivity, agents that natively speak MCP will have massive ecosystem advantages over those that need adapters.”
“The moment when an open model matches closed web agents on benchmark performance is coming faster than the incumbents expected — MolmoWeb at 8B parameters beating GPT-4o-based systems is a preview. More importantly, the complete open data release sets a precedent: now anyone can study why web agents fail, fix it, and share those improvements. That's how open-source ecosystems compound.”
“For creators who work with sensitive client material — brand assets, unreleased campaigns, personal client data — the local-first guarantee removes the biggest barrier to using AI agents professionally. I can let Goose read my project files without wondering if they'll appear in someone's training data.”
“For most creators the use case is still too narrow — a web agent that navigates browsers from screenshots sounds magical until you realize login flows and interactive rich media are out of scope. There's real potential for automating research, content gathering, and form filling, but the reliability bar for everyday creative workflows isn't there yet. Watch this space in 6 months.”
