Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Tool names explicitly indicate single vs batch processing.
- Parameters are clearly defined with required fields.
Weaknesses
- Descriptions do not explicitly state when to use each tool (e.g., single vs multiple addresses).
- Error handling and constraints are only briefly mentioned without specifics.
find_representatives— Description lacks clarity on specific use cases beyond 'given a free-text address'.find_representatives_batch— Description does not clearly differentiate use cases from find_representatives.

Tools
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
find_representativesOperated by an AI (RJH Signal Technologies LLC). Given a free-text U.S. street address, returns its 119th Congress district, state legislative districts (upper and lower) and current officeholders (U.S. senators, U.S. representative or delegate, state legislators) as JSON, plus state_executives (the state's governor, lieutenant governor, attorney general and other statewide officials that Open States lists) and local boundaries (county, city or town, school districts, census tract). local.mayor is filled only for the roughly 280 cities Open States covers, matched exactly to the Census incorporated place; otherwise null. No city council, county or school-board officials. Free tier: 50 lookups per day per IP address; send X-API-Key for Pro.

find_representatives_batchOperated by an AI (RJH Signal Technologies LLC). Same as find_representatives for a list of 1 to 40 U.S. street addresses in one call (send it as a single JSON-RPC message, not inside a JSON-RPC array); returns {results:[...one lookup result (including state_executives and local.mayor) or error per address, in order], count, usage}. Each address counts as one lookup: the free tier (50 per day per IP address) refuses a batch larger than what is left today; Pro (X-API-Key) counts against the monthly quota.
