Validate, repair, schema-check, and diff JSON for reliable AI agent state.
This MCP tool is described as performing local JSON validation, repair, and schema checks, with no stated need for credentials or remote network egress. It is open-source under MIT, but the source comes via a third-party registry with low adoption and unknown maintenance, so overall risk is low with some caution around local execution and supply-chain maturity.
The materials explicitly state that no keys or environment variables are required, and there is no indication that the tool requests account credentials, API tokens, or other sensitive authentication data; credential exposure risk appears low.
The materials list no remote endpoints, and the description focuses on local JSON validation, repair, and diffing, with no evidence that user data is sent to external services.
The system checks indicate that this tool executes code; as an MCP tool, this generally means local runtime execution. The available materials do not show requests for unusual system privileges or execution capabilities beyond its stated purpose, so this fits normal caution rather than high risk.
By function, the tool likely needs to read and possibly write JSON content to validate and repair it; this is routine data access for the stated purpose. The materials do not indicate access to sensitive directories, system resources, or broad datasets beyond JSON handling.
Positive factors include being open-source, auditable, and MIT-licensed. However, it is distributed via a third-party registry, the GitHub repository shows 0 stars, maintenance status is unknown, and the absence of a README reduces audit context, so project maturity and dependency hygiene warrant caution.

No copy-paste install info for "json-sanity" yet — see the docs or source repo.
Please validate and repair the following JSON, returning a valid version without changing its meaning: {"user":"Ava","tasks":["draft", "review",],"done":falseReturns valid repaired JSON and explains which syntax issues were fixed.
Please validate this JSON against the schema; if invalid, report errors and generate a minimally repaired version. Schema: {"type":"object","properties":{"id":{"type":"string"},"score":{"type":"number"}},"required":["id","score"]} JSON: {"id":123,"score":"91"}Outputs validation results, a field error list, and a minimally modified repaired JSON.
Please compare these two JSON objects and list added, removed, and changed fields clearly. Old: {"status":"open","tags":["bug"],"priority":1} New: {"status":"closed","tags":["bug","ui"],"priority":2}Returns a structured diff summary with field-level changes and before/after values.
Repair JSON and validate schemas for reliable AI agent outputs.
Generate, validate, format, and manipulate JSON data structures easily.
Repair broken or malformed JSON for easier parsing, debugging, and downstream use.
Validate JSON data against JSON Schema standards quickly and reliably.
Validate, clean, transform, and merge structured data and text datasets.
