Description

Fair Odds Calculator: the site's own MCP server — dataset; every answer cites the site.

What our measurements say

com.fairoddscalculator/site is a remote MCP server published at fairoddscalculator.com. It has been probed 8 times since 9/12/2026. It answered in 8 of them (100.0%), a near-uninterrupted record. Median response time is 949 ms, a delay an agent will notice. It offers a narrow, focused set of 7 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.

Agent readability score

Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.

Agent readability score

Clear tool names and specific use cases, but some parameter ambiguity and missing error details.based on measured tool list

Strengths

Tool names clearly indicate their purpose (e.g., dataset_search for querying rows).
Descriptions specify use cases (e.g., dataset_compare for 'X vs Y' questions).

Weaknesses

Some parameters lack explicit type constraints (e.g., dataset_row's 'value' is a string, but column may be numeric).
Error handling and edge cases (e.g., invalid column types) are not explicitly documented.

dataset_stats — Description mentions numeric columns but doesn't enforce type validation in parameters.
dataset_row — Value parameter is a string, but column may be numeric (potential type mismatch).
dataset_search — No explicit mention of handling non-matching queries or empty results.

Verdict

Tools are well-structured with clear intent, but parameter type ambiguity and limited error documentation reduce reliability. Puan (75/100) aligns with clear naming but gaps in robustness.

Event narrative

Server in legacy era with 100% compliance, smoke status unknown.

Risk: low

2026-09-12T15:21:42.024Z — Legacy era active, compliance score 100, smoke status null · Perfect compliance but missing smoke test validation

Advice

Investigate smoke test configuration. Monitor for unexpected status changes. Maintain legacy system until migration planning is complete.
