Restart MCP Server

restart_server
Destructive

Restart the MCP server: terminates Proton Bridge, shuts down gracefully, and spawns a fresh process. Re-launches Bridge automatically if enabled. Requires confirmation.

Instructions

Restart the MCP server. Terminates Proton Bridge, shuts down gracefully, then spawns a fresh server process. If autoStartBridge is enabled the new process will re-launch Bridge automatically. Requires { confirmed: true }.

TDQS

A4.5/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already indicate destructive and non-idempotent behavior. The description adds valuable context: termination of Proton Bridge, graceful shutdown, spawning a new process, and autoStartBridge behavior. No contradictions with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is three sentences with no wasted words. It front-loads the purpose, then explains the process and a key requirement. Ideal length and structure.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a server restart tool with 2 parameters, good schema/annotation coverage, and an output schema present, the description covers behavior, confirmation requirement, and auto-bridge nuance comprehensively. No gaps identified.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with both parameters well described. The description reinforces the 'confirmed' parameter but adds no new semantic meaning beyond the schema. Baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool restarts the MCP server with specific actions (terminate, shut down, spawn fresh process). It distinguishes from siblings like shutdown_server (which only shuts down) and start_bridge (which only starts Bridge).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly requires 'confirmed: true', providing a clear precondition. However, it does not directly compare to sibling tools like shutdown_server or start_bridge, leaving some ambiguity about when to use this vs alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
