Mountaineers MCP Server

by dreamiurg

search_courses

Find upcoming courses, clinics, and seminars by query, activity type, branch, difficulty, or open registration status.

Instructions

Search currently-published courses, clinics, and seminars on mountaineers.org (upcoming and rolling-enrollment only). Past course instances (prior years) are NOT in the search index, even though their URLs still resolve — if you have a known historical course URL use get_course, or use get_my_courses for the authenticated user's past courses.

Behavior4/5

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

With no annotations, the description carries full burden and discloses that past courses are not in the index and that URLs can still resolve but search won't find them. However, it does not mention authentication, rate limits, or pagination behavior beyond what's in the schema.

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?

Two sentences: first defines purpose and scope, second provides exclusions and alternatives. No wasted words, front-loaded with key information.

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?

Adequately covers the key constraint of only current offerings. Lacks details on return format (no output schema) but the schema explains pagination. For a search tool, this is mostly complete.

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?

Schema coverage is 100%, but the description adds context about the date scope (upcoming and rolling-enrollment only) and exclusions, which goes beyond schema parameter descriptions.

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 tool searches 'currently-published courses, clinics, and seminars' on a specific site, and distinguishes it from siblings like get_course and get_my_courses by specifying scope and alternatives.

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

Usage Guidelines5/5

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

Explicitly says when to use (search current offerings) and when not to use (past instances), and provides alternative tools (get_course, get_my_courses), giving clear guidance.

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