Tally MCP Server

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

With no annotations provided, the description carries full burden but offers minimal behavioral insight. It states it's an update operation (implying mutation), but doesn't disclose permissions required, whether it overwrites or merges settings, error conditions, or what happens to unspecified fields. For a mutation tool with zero annotation coverage, this leaves significant gaps.

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?

The description is a single, clear sentence with zero wasted words. It's front-loaded with the core action and resource, making it easy to parse quickly. Every word earns its place without being overly terse.

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 4 parameters, no annotations, and no output schema, the description is inadequate. It doesn't cover behavioral aspects like side effects, error handling, or response format, nor does it provide usage context. The 100% schema coverage helps with parameters, but overall completeness is poor given the tool's complexity.

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 parameters are fully documented in the schema. The description adds no additional parameter context beyond implying 'update' involves modifying fields. It doesn't explain relationships between parameters (e.g., that 'events' and 'url' are optional updates) or provide examples, so it meets the baseline but doesn't add value.

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') and resource ('an existing webhook'), making the purpose immediately understandable. It distinguishes from sibling tools like 'create_tally_webhook' by specifying 'existing', but doesn't differentiate from other update tools like 'update_form_settings' or 'update_tally_form' beyond the resource type.

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?

No guidance is provided on when to use this tool versus alternatives. The description doesn't mention prerequisites (e.g., needing a webhook ID), when not to use it, or how it differs from similar tools like 'configure_form_notifications' or 'create_tally_webhook' beyond the basic update action.

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