MCP SSH Manager

ssh_db_list

List databases on a remote server, or list tables (SQL) and collections (MongoDB) for a given database. Supports MySQL, PostgreSQL, and MongoDB. Read-only operation.

Instructions

Lists database objects on the remote server for the given engine without modifying anything. When database is provided it lists the tables (SQL) or collections (MongoDB) of that database; when omitted it lists all databases with common system databases filtered out. Supports mysql, postgresql, and mongodb. Returns the items and a count. Read-only and safe to call repeatedly.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

A4.4/5.0

Behavior4/5

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

With no annotations provided, the description carries the full burden and does well by stating the operation is non-modifying, read-only, safe to call repeatedly, and filters system databases. It could add details about authentication or error behavior, but the key behavioral traits are disclosed.

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 compact sentences, front-loaded with the core purpose and safety guarantee. Every sentence earns its place, and there is no redundant phrasing or repeated schema content.

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

Completeness4/5

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

For a list-style tool with no output schema, the description covers purpose, parameter-dependent behavior, supported engines, return shape, and safety profile. It could mention how credentials are resolved or what happens on connection failure, but nothing critical is missing for selecting and invoking the tool.

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

Parameters4/5

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

The schema documents all parameters with descriptions, so the baseline is 3. The description adds meaningful context beyond the schema by explaining how the 'database' parameter changes behavior, which engines are supported, and what the return payload contains.

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 uses a specific verb ('Lists') with a clearly defined resource ('database objects on the remote server') and states it modifies nothing. It also distinguishes its behavior from siblings like ssh_db_query, ssh_db_dump, and ssh_db_import by focusing on introspection only.

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 gives clear usage context: when 'database' is provided it lists tables/collections, and when omitted it lists databases with system databases filtered out. It also notes the tool is read-only and safe to call repeatedly, but it does not explicitly name alternatives or state when to prefer another tool.

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