How Geometry MCP Works

how_geometry_works
Read-only

Free starting guide for the DaedalMap geography/geometry MCP. Call this first to learn the durable loc_id, administrative-spine, reference-family, discovery, point-lookup, and bounded-shape concepts. Then read the live geometry catalog for country-specific depths, families, and query guidance, and use get_tool_help for one exact tool. Current catalog: The same geography tools work worldwide across a cataloged baseline of 252 geographic entities, reaching up to Admin 2. Where additional country releases are available, the same calls automatically return deeper administrative tiers or maintained reference families. Additional detail is currently available for Australia, Brazil, Canada, France, Germany, Mexico, United Kingdom, United States.

A4.3/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true, and the description adds helpful behavioral context: this is a free guide, it should be invoked first, and it explains automatic deeper administrative tiers where available. It does not describe the response format, but that is less critical for a help/guide tool. No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured and front-loaded with the key instruction to call this first. It then provides a logical flow to other tools and includes current catalog data. It is somewhat longer than strictly necessary, but the extra detail about country coverage and automatic depth behavior is relevant and earns its place.

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 an onboarding/guide tool, the description covers the conceptual scope, the recommended sequence, and the current catalog breadth across countries and admin levels. It does not state what the response looks like or the exact phrasing of the optional question parameter, but given the tool's purpose and the fully documented schema, this is sufficient.

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?

The input schema already provides 100% coverage of the single optional parameter with a clear description ('Optional natural-language question about how to use the geometry tool family'). The tool description does not add additional parameter-level guidance, so the baseline score of 3 is appropriate.

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 identifies this as a starting guide, specifies the actionable directive to call it first, and enumerates the concepts it teaches (loc_id, administrative-spine, reference-family, discovery, point-lookup, bounded-shape). It explicitly differentiates itself from sibling tools like read_geometry_catalog and get_tool_help by describing their distinct roles.

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?

It provides explicit workflow guidance: call this first to learn concepts, then read the live geometry catalog for country-specific guidance, and use get_tool_help for one exact tool. This directly tells the agent when to use this tool versus the alternatives, leaving no ambiguity.

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

A4.2/5.0
Disambiguation5/5

Each tool has a clearly distinct purpose: point resolution, reference conversion, hierarchy traversal, geometry retrieval, export creation, job estimation, catalog discovery, and relationship comparison are all separated. The descriptions explicitly state what each tool does and what it does not do, preventing misselection. Even closely related tools like get_geometry, get_geometry_export, and estimate_geometry_package are differentiated by their roles (single-shape retrieval vs. export artifact vs. dry-run estimate).

Naming Consistency5/5

All 20 tool names follow a consistent verb_noun snake_case pattern (e.g., get_geometry, create_conversion_job, resolve_point, list_reference_systems). The verbs are action-oriented (get, create, estimate, resolve, compare, list, read) and each noun clearly indicates the subject. While a few like 'loc_id_info' and 'how_geometry_works' deviate slightly from the strict verb_noun structure, they still fit the overall style and are easy to predict.

Tool Count4/5

The 20 tools are slightly above the typical 3-15 range but still well-scoped for a comprehensive geocoding and geography service. The extra tools reflect the breadth of operations offered (discovery, conversion, estimation, export, resolution, relationship analysis), each earning its place. The count feels reasonable given the domain, though it approaches the upper boundary of what an agent might easily navigate.

Completeness5/5

The tool surface covers the full lifecycle of geocoding workflows: discovery (get_catalog, get_pack, read_geometry_catalog), point resolution (resolve_point), reference resolution (resolve_reference), identifier identification (identify_reference_system), hierarchy traversal (resolve_loc_id_scope, loc_id_info), geometry retrieval (get_geometry), relationship analysis (compare_geographies), conversion (convert_reference, create_conversion_job), export (create_geometry_export), and estimation (estimate_geometry_package, estimate_conversion_job). The inclusion of help tools (get_tool_help, how_geometry_works) and job status retrieval ensures no dead ends. The absence of destructive or update operations is consistent with a read-only geospatial data service, so the surface is appropriate.
