What is OMNI

OMNI is an MCP server preloaded with 500+ optimized, pre-tested tools — Google Workspace, Microsoft 365, Slack, GitHub, Linear, and the rest of the daily-driver SaaS — all on a single connection.

Instead of loading every tool definition into the model up front, your agent sees three meta-tools and pulls in exactly the tools a task requires, ranked by semantic relevance.

The plumbing disappears: no pickers, no narration, no asking which integration to use. OMNI handles discovery, execution, and the OAuth handshake underneath.

The Interface

SEARCH()
Describe the task in plain language. Returns the most relevant tools with input schemas inline — ready to call immediately, no follow-up round trip.
CALL()
Invoke any tool the search surfaced, with arguments matching its schema. Execution runs against Arcade's engine and returns the result.
AUTHORIZE()
When a tool needs OAuth, OMNI runs the handshake, reconnects providers, switches accounts, and repairs scopes — no tribal knowledge required.

Advisory

OMNI is a research preview from Arcade Labs, where Arcade's engineering team shares experiments in public. It is not a supported product: it ships as-is, with no warranty, and the service may change or break on any update. Found an issue? Tell us on Discord — we address things on a best-effort basis.
