Repair JSON and validate schemas for reliable AI agent outputs.
This MCP tool has positive supply-chain signals: it is listed in an official registry, open source, and recently updated. It executes code locally and connects to x402.agentfund.net, and its pay-per-call design warrants caution, but the provided materials do not show concrete red flags sufficient for a high-risk rating.
The materials explicitly state that no keys or environment variables are required; there is no evidence that users must provide an API key or other long-lived secrets. The description mentions USDC/Base/x402 payment flow, but the provided materials do not indicate custody of private keys or import of sensitive credentials.
System checks show outbound access to the remote endpoint x402.agentfund.net. Its pay-per-call JSON repair/schema validation design suggests submitted content may be sent to that endpoint. The endpoint is declared and appears related to the stated function, but the lack of a README prevents confirmation of exact payload scope and retention behavior.
The tool is flagged as executes-code, meaning it runs code/processes locally, which is a normal property of MCP tools. The available materials do not show requests for unusual system privileges or execution behavior unrelated to its stated purpose.
To perform JSON repair and schema validation, the tool may access user-supplied JSON/schema content; however, the materials do not specify which local files, directories, or other resources it can read or write. There is no explicit evidence of overbroad access, but the missing documentation leaves the data-access boundary unclear.
It comes from an official registry and has a public GitHub repository with updates within the last year, which are positive risk-reducing signals. However, the missing README, undeclared license, and extremely low adoption (0 stars) limit auditability and maturity, so caution is more appropriate than a low-risk rating.
