Preview & research

Addon marketplace: research status.

Connect known tools directly; do not assume a public marketplace or audited package catalog exists.

ResearchReviewed September 2026

What changed in the documentation

Older pages presented addon discovery and installation as an available public marketplace. The current CLI labels marketplace functionality as Research.

A local manifest or compatibility command does not establish an available registry, trusted publisher or hosted entitlement.

Connect an existing tool

If you already know the downstream MCP server you want, use MCP connections. Inspect its command, URL, credentials and tool permissions before enabling it.

For structured data, start with data sources.

Build an extension deliberately

Use the relevant local plugin or provider contract, pin versions and verify the exact execution boundary. Do not describe a sandbox or security review that has not been established for that extension.

For embedding in a product, the SDK has a distinct versioned surface and license.
