Open MCP Config Manager

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

No annotations are provided, so the description must carry behavioral disclosure. It discloses that the tool opens an interactive panel, involves viewing/editing config, and can add/remove/update servers, which signals user-in-the-loop and potential writes. It does not mention whether changes are applied immediately or require user confirmation, but for a launcher-style tool this is reasonably transparent.

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

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

A single sentence that front-loads the action ('Open an interactive panel') and packs the capabilities and advantage into a concise parenthetical. No filler.

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

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

For a no-parameter, no-output-schema tool, the description covers the core action, resource, and effects. The only material gap is explicit usage rules versus sibling tools, which is already reflected in the usage_guidelines score.

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

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

The input schema has zero properties, so there are no parameter semantics to clarify. The description's functional explanation is sufficient; no parameter documentation is needed.

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

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

States a specific verb ('Open') and resource ('interactive panel... MCP server configuration'), and enumerates add/remove/update capabilities. This clearly distinguishes it from sibling tools like read-mcp-config or write-mcp-config, which operate directly on config data rather than launching an interactive panel.

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

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

The description implies the tool is for interactive, user-driven configuration management ('interactive panel', 'without editing...by hand'), which contrasts with programmatic sibling tools. However, it never explicitly states when to choose this over read-mcp-config/write-mcp-config or that it is unsuitable for automated/headless use.

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