MCP Path

Gemini Sidecar start

Gemini Sidecar start is a public reference for embedded agent runtimes and runtime communication. It names the signal, policy, or flow an agent should understand before choosing a concrete tool.

Catalog path

Reference page for a documented MCP capability path.

Type: MCP path
Family: Sidecar Agent Orchestration (Embedded Runtimes)
Effect: changes state
Status: Reference
Path: 47.3

Purpose

What this entry explains

What it does

This reference explains Gemini Sidecar start for embedded agent runtimes and runtime communication. It is kept as a named reference so agents can cite the flow without inventing a tool name.

Use when

Use this entry when an agent needs to carry out the bounded step "Gemini Sidecar start" for embedded agent runtimes and runtime communication.
Use it as a reference path when the catalog describes a capability but no single public tool name is explicit.
Use it before chaining follow-up tools so the next step is based on current evidence.

Reference Use

How agents should cite and apply this area

Examples are maintained at family level and use only public tool names or reference paths already present in the catalog.

Signal, gate, behavior, boundary

Gemini Sidecar start describes a behavior for embedded agent runtimes and runtime communication. The path shows which signal, gate, behavior, or boundary must be checked before choosing a concrete tool.

When agents cite it

An agent cites this path when it needs Gemini Sidecar start as context for a decision, block, target check, or follow-up tool choice.

Why no callable name

The public source does not name one callable tool for this path. The documentation therefore keeps it as a reference path and does not invent a callable name.

Signals and rule

Relevant response signals: current discovery and actual response status. Safety axes: Browser state. The reference path alone is not permission to execute. Before acting, check current MCP discovery, visible target, scope, and the actual response.

Family example

An agent prepares a bounded run in embedded agent runtimes and runtime communication and must keep scope, progress, and stop condition visible.

The agent starts with Claude Sidecar start, reads the current response or reference, and only then chooses the concrete next tool.

Claude Sidecar start Codex Sidecar start Gemini Sidecar start

Scope, budget, progress, stop condition, and terminal status remain part of the run.

Contract

Inputs and important response fields

This page is a public reference. Agents and integrators should still read current MCP tool discovery before execution, because schemas can be gated by settings or version.

Inputs

No stable public input field is derived from the catalog source for this path. Read current MCP discovery before execution.

Response fields

No fixed public response field is derived from the catalog source for this path. Use current tool discovery and the actual response before chaining the next step.

Safety

Boundary before execution

Effect

Can change browser, page, or workflow state. The target and expected result must be clear before execution.

Agent rule

Confirm the current target first, perform only the intended bounded action, and verify the resulting page or workflow state afterwards.

Human control

For humans, this entry names the browser or workflow state in embedded agent runtimes and runtime communication that may change, so the action can be reviewed before and after execution.

High-Impact Review

Execution boundary and recheck hints

Review category: Plugin runtime

Execution boundary

Plugin code and runtime calls stay limited to explicitly approved tools, permissions, and target contexts.

Typical false assumption

False assumption: an installed or loaded plugin may use all available browser data.

Visible user control

Approval, active tab, permission, and test result must remain visible user controls.

Agent rule

Execute plugin capabilities only after current tool discovery and permission checks; do not blindly chain external runtime output.

Abort or recheck

Recheck when permissions are missing, a plugin is unknown, or runtime status diverges from expected scope.

Safety Axes

How this path can affect work

Axes are stable catalog signals for humans, agents, and LLM discovery. One path can carry several axes.

Browser state browser_state_change

Changes tab, navigation, focus, claim, scroll position, window state, or browser environment.

Confirm the target context visibly before execution and verify that the expected browser state was reached afterwards.
