France Data MCP

reverse_geocode

Read-onlyIdempotent

Convert GPS coordinates into a street address. Provide latitude and longitude to get the nearest address from French official geographic data.

Instructions

Géocodage inverse : à partir de coordonnées GPS, retrouve l'adresse la plus proche. Source : IGN Géoplateforme.

Behavior3/5

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

Annotations provide strong safety guarantees (readOnlyHint=true, destructiveHint=false, idempotentHint=true). The description adds the data source (IGN Géoplateforme) but no additional behavioral details like limits or response structure.

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?

The description is extremely concise and front-loaded with the core purpose. Every word is justified, and there is no unnecessary information.

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?

The description mentions the output is the 'nearest address' but provides no details on structure. Without an output schema, more detail would be beneficial, but for a simple tool it may be adequate.

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 coverage is 100% with descriptions for both parameters. The description adds context that coordinates are GPS but does not enhance parameter understanding beyond the 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 tool's purpose: reverse geocoding from GPS coordinates to find the nearest address. It implicitly distinguishes from sibling 'geocode_adresse' which does forward geocoding.

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 usage for obtaining addresses from coordinates but does not explicitly state when to use this tool over alternatives or provide exclusions.

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