AgentID is a portable identity layer for AI agents that persists a single name, memory, belief set, and rule system across Claude, ChatGPT, Cursor, GitHub Copilot, Cline, and any MCP-compatible client. Instead of re-prompting each tool independently, you define an agent once and it shows up consistently wherever you work. It includes multi-agent task coordination and real-time status broadcasting for team environments. The system includes automatic system prompt compression that reduces token consumption by up to 65% — a meaningful cost reduction for teams running persistent agents across multiple sessions. Memory entries, beliefs, and rules all synchronize in real-time via a central AgentID hub accessible through a browser interface. The product is positioned at the boundary between AI tooling and human identity, raising interesting questions about agent ownership and portability. The free tier offers one identity with three agents and 50 memory entries — enough for serious individual use.

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.
Reviewer scorecard
“The cross-tool identity persistence is genuinely useful for teams using multiple AI coding assistants. The 65% token reduction from prompt compression has real cost implications at scale. The MCP compatibility means it plugs into your existing workflow without rearchitecting anything.”
“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.”
“Centralizing agent identity on a third-party service creates a single point of failure for your entire AI workflow. If AgentID goes down or changes pricing, your agents lose their memory and context. The 65% token reduction claim also needs independent verification — prompt compression quality varies enormously.”
“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.”
“Portable agent identity is a missing primitive in the current AI tooling stack. Right now, every tool reinvents context management independently — AgentID's model of owning a persistent identity that travels across tools is the right long-term architecture for human-AI collaboration.”
“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.”
“For creators managing multi-tool AI workflows across research, writing, and production, having a consistent 'creative assistant' identity that remembers your preferences and style across every tool is genuinely transformative. This reduces the 'cold start' problem on every new session.”
“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.”
