This MCP server provides deterministic analysis of data serialization formats. It helps developers choose the most efficient way to store or transmit data by comparing JSON, YAML, and CSV. Use compare_serialization_sizes to get exact byte counts and token estimates, or get_format_efficiency_summary to identify the best format for your specific data structure. It also includes validate_data_for_serialization to ensure your objects are safe for comparison.

3 tools expose this connector's capabilities to your AI agent.

compare_serialization_sizes

How much space and how many tokens will my data consume in JSON, YAML, and CSV formats?

get_format_efficiency_summary

Which format is most efficient for my specific data structure type?

validate_data_for_serialization

Is this data object safe to compare using the serialization tools?

See how to talk to your AI agent using Serialization Size Comparator.

How much space will this data consume in JSON, YAML, and CSV? {"id": 1, "name": "test", "tags": ["a", "b"]}

{"jsonBytes": 45, "yamlBytes": 33, "csvBytes": 22, "jsonTokens": 11, "yamlTokens": 8, "csvTokens": 5, "recommendedFormat": "CSV", "savingsPercent": 51.1}

Which format is most efficient for this nested object? {"user": {"id": 1, "meta": {"active": true}}}

{"isNested": true, "preferredFormat": "YAML", "estimatedSpaceReduction": 25}

Is this data object safe to compare? {"key": "value"}

{"isValid": true, "reason": ""}

The YAML size is estimated as 75% of the JSON byte size, accounting for the removal of structural characters like braces and quotes.
