Install your first plugin
Connect a service, inspect readiness, and run your first tool with real CLI commands.
Pick a service
Open the Plugin catalog and pick one you use. This guide uses Linear as the example, but the same inspect/exec pattern applies to any ready source.
Install and authorize
Use the Harbor Cloud dashboard Install page for guided install and OAuth. The public CLI does not expose a top-level plugin install command.
If a source is present but needs OAuth, inspect can return the setup URL:
hrbr inspect 'return await hrbr.sources.oauthStart({ namespace: "linear-mcp" })'Inspect source readiness
hrbr inspect 'return await hrbr.sources.list()'Look for a ready source and its runtime namespace. If it is not ready, finish the setup step before executing.
Search tools
hrbr inspect 'return await hrbr.tools.search({ query: "linear list issues", limit: 5 })'The search result includes callable examples and type details. Copy the returned JavaScript call shape instead of guessing tool names.
Run a tool
hrbr exec 'return await linearMcp.listIssues({ limit: 3 })'The execution returns TOON-formatted output and records a trace.
