Enterprise-grade JSON processing suite — format, validate, deep-diff, JSONPath query, structural transform, and schema generation in one MCP server. Use when...
Usage Guidance
This skill appears to be a thin wrapper that sends the JSON you provide to a third-party Cloudflare Workers endpoint for processing. Before installing or using it: (1) Do not send sensitive or confidential JSON (secrets, credentials, PII) to this skill until you verify the service's privacy/retention policy. (2) Ask the publisher for the server's source code or a self-hosting option (so you can run the MCP on infrastructure you control). (3) Verify the endpoint's provenance (who runs yagami8095.workers.dev and the linked GitHub repo) and ask for a security/privacy statement. (4) If you need safe, auditable processing, prefer local tools or a skill that runs entirely inside the agent without sending data to external hosts. If you proceed, test first with non-sensitive example data and confirm that the skill only sends what you expect.
Capability Analysis
Type: OpenClaw Skill
Name: openclaw-json-toolkit
Version: 2.0.0
The skill bundle provides a comprehensive set of JSON utility tools (formatting, validation, diffing, and querying) via a remote MCP server hosted on Cloudflare Workers (json-toolkit-mcp.yagami8095.workers.dev). The instructions in SKILL.md are clearly aligned with the stated purpose of JSON processing and do not contain any prompt injection attempts, hidden data exfiltration commands, or malicious logic. While the tool processes user-provided JSON on a third-party platform, this is transparently documented as its primary operational model.
Capability Assessment
Purpose & Capability
The name and features (format, validate, diff, query, transform, schema generation) align with the commands and parameters in SKILL.md. However, registry metadata declared no homepage/source while SKILL.md embeds a homepage and a specific external MCP endpoint (https://json-toolkit-mcp.yagami8095.workers.dev/mcp). That mismatch in provenance and the reliance on a remote service should be justified by the author.
Instruction Scope
SKILL.md is instruction-only and explicitly directs clients to use a streamable-http MCP server at a third-party Cloudflare Workers URL. At runtime the agent will forward user-supplied JSON to that external endpoint for processing. There is no disclosure about logging, retention, or privacy, and no local-processing fallback described. The 'read_when' triggers combined with normal autonomous invocation could cause user JSON (potentially sensitive) to be sent automatically.
Install Mechanism
No install spec and no files to install — lowest-risk delivery mechanism. The skill is instruction-only and does not write code to disk.
Credentials
The skill requests no environment variables, credentials, or config paths. That is proportionate to an instruction-only skill that delegates processing to a public endpoint. (Note: it is somewhat unusual that a third-party hosted service claims 'No API key needed' — this is a design choice but not intrinsically inconsistent.)
Persistence & Privilege
always:false and no config or credential modifications — normal. However, because model invocation is allowed (default), the combination of autonomous invocation + an external endpoint increases the risk that user data is forwarded without explicit, informed consent. The skill does not request persistent privileges but does rely on network I/O to a specific external host.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install openclaw-json-toolkit - After installation, invoke the skill by name or use
/openclaw-json-toolkit - Provide required inputs per the skill's parameter spec and get structured output
