Unofficial HPO MCP Server

batch_get_hpo_terms

Retrieve up to 20 HPO terms in one request using their IDs, streamlining batch lookups of phenotypic terms for genetic research.

Instructions

Retrieve multiple HPO terms in a single request (maximum 20 terms)

Input Schema

Behavior2/5

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

No annotations provided. The description only discloses the max batch size (20). It omits error behavior, authorization needs, or what happens with invalid IDs. Minimal behavioral disclosure.

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?

Single sentence with no redundancy. Front-loaded key information (action, resource, limit). Every word is necessary.

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

Completeness3/5

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

No output schema; description does not mention return format (list of terms, errors). Lacks authentication or prerequisites. Adequate but incomplete for a batch tool.

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 covers all parameters (100% coverage). The description adds max batch size, which is also in schema's maxItems. No additional meaning beyond schema.

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 action (Retrieve), resource (HPO terms), and batching constraint (multiple, max 20). It distinguishes from the single-term sibling get_hpo_term.

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

Usage Guidelines3/5

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

The description implies batching multiple terms but does not explicitly state when to use this over alternatives like get_hpo_term or search_hpo_terms. No when-not or alternative guidance.

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