Easy Notion MCP

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

With no annotations, the description carries the full burden. It discloses key behavioral traits: it's a mutation tool (implied by 'Update'), uses partial updates (omitted properties unchanged), and references format consistency with 'add_database_entry'. However, it lacks details on permissions, error handling, or response format.

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?

Three concise sentences with zero waste: the first states the purpose, the second explains the partial update behavior, and the third provides usage guidance. It is front-loaded and efficiently structured.

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 mutation tool with no annotations and no output schema, the description is adequate but has gaps. It covers purpose, partial update behavior, and references for property details, but lacks information on permissions, side effects, or what the tool returns, which are important for safe invocation.

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?

Schema description coverage is 100%, so the schema already documents both parameters. The description adds marginal value by explaining that 'properties' uses a 'key-value property map' and references 'get_database' for valid options, but does not provide syntax or format details beyond the schema.

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?

The description clearly states the action ('Update'), the target ('an existing database entry'), and the scope ('only the properties you want to change'), distinguishing it from siblings like 'add_database_entry' (creation) and 'delete_database_entry' (deletion).

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?

It provides clear context on when to use this tool (for partial updates) and references 'get_database' for valid properties, but does not explicitly state when not to use it or name alternatives like 'replace_content' or 'update_page' for other update scenarios.

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