Open by protocol

We extracted these packages from a platform that speaks open standards. Agents connect the same way you build, with no proprietary lock-in.

Model Context Protocol
Point an agent at any remote MCP server and use its tools.
A built-in catalogue includes DeepWiki and GitMCP.
Agent-to-Agent (A2A)
Every agent ships an A2A agent card (spec v0.3.0) over JSON-RPC.
Agents delegate work to one another across your workspace.
REST, OpenAPI & SDK
Connect any REST API. discover_api maps OpenAPI or Swagger specs.
Fallback is raw HTTP, plus SDK entity discovery for GitHub and Railway.
59 providers, 75 services, 512 operations
The registry spans CRM, project management and comms plus email and storage.
Dev tools, payments and accounting plus ecommerce, design and forms and signing.
