OpenClaw JSON Toolkit v2.0

The Swiss Army knife for JSON — 6 tools, zero install, instant results.

Quick Reference

What's New in v2.0

• :zap: CloudEdge Protocol -- All processing runs on Cloudflare's global edge network. Sub-100ms response worldwide, zero cold starts.
• :mag: DeepQuery Engine -- Full JSONPath with deep scan (..), wildcards (*), filter expressions (?(@.price < 10)), and array slicing ([0:5]).
• :shield: Schema Draft-07 Intelligence -- Auto-detects semantic formats: email, URI, date-time, IPv4, UUID. Infers required fields and enum candidates from sample data.
• :arrows_counterclockwise: StructureMorph Transform -- Recursive flatten/unflatten, key renaming with mapping objects, pick/omit projections on arbitrarily nested JSON.

MCP Quick Start

{
  "openclaw-json": {
    "type": "streamable-http",
    "url": "https://json-toolkit-mcp.yagami8095.workers.dev/mcp"
  }
}

Add to Claude Desktop, Cursor, Windsurf, VS Code, or any MCP-compatible client. No API key needed for Free tier. Works immediately.

Detection Triggers

This skill activates when you say:

• "format this JSON" / "pretty print this" / "indent this JSON"
• "validate my JSON" / "is this valid JSON" / "why won't this parse"
• "compare these two JSON" / "diff these objects" / "what changed between these configs"
• "query this JSON" / "extract from JSON" / "JSONPath" / "get the nested value"
• "flatten this JSON" / "restructure this" / "rename these keys" / "unflatten"
• "generate a schema" / "create JSON Schema" / "schema from this sample"

Tools (6)

json_format -- Pretty-Print & Minify (CloudEdge Protocol)

Format any JSON string with configurable indentation or compress to a single line for production payloads.

Output: Formatted JSON string + byte count (before/after) + compression ratio when minifying.

WRONG vs RIGHT

WRONG -- Manually adding spaces to JSON in a text editor:

User: Can you add proper indentation to this JSON?
Agent: *manually edits text, misses nested arrays, breaks trailing commas*

RIGHT -- Use json_format:

User: Format this JSON
Agent: calls json_format → returns perfectly indented JSON with byte count in 12ms

json_validate -- Validation with Diagnostics

Validate JSON syntax and get structural metadata on success, or precise error location on failure.

On success: { valid: true, type: "object"|"array", keyCount, depth, byteSize } On failure: { valid: false, error: "message", line: 3, column: 15, context: "near '...'" }

WRONG vs RIGHT

WRONG -- Guessing where the JSON error is:

User: Why won't this JSON parse?
Agent: *scans visually, says "maybe line 12?"* — misses the real error on line 47

RIGHT -- Use json_validate:

User: Why won't this JSON parse?
Agent: calls json_validate → "Unexpected token at line 47, column 23: trailing comma after last element"

json_diff -- Structural Comparison (DeepDiff Protocol)

Compare two JSON values and get a complete structural diff showing every added, removed, and changed path.

Output: { added: [...paths], removed: [...paths], changed: [{ path, from, to }], totalChanges }. Every changed value shows the exact before/after values at that path.

• Use for: API response comparison, config drift detection, schema evolution tracking, deployment validation.

json_query -- JSONPath Extraction (DeepQuery Engine)

Query JSON with full JSONPath support including dot notation, bracket notation, wildcards, deep scan, array slicing, and filter expressions.

Supported syntax:

• $.store.book[0].title -- direct path
• $.store.book[*].author -- wildcard
• $..price -- recursive deep scan
• $.store.book[0:3] -- array slicing
• $.store.book[?(@.price < 10)] -- filter expression

Output: Array of matched values with their resolved paths.

json_transform -- Structural Operations (StructureMorph)

Perform structural transformations: flatten nested JSON to dot-notation keys, unflatten back, pick/omit specific keys, or rename keys with a mapping object.

Output: Transformed JSON with operation summary (keys affected, depth change).

json_schema_generate -- Schema from Samples (Schema Intelligence)

Generate a complete JSON Schema (draft-07) from any JSON value. Auto-infers types, detects semantic formats, determines required fields, and identifies enum candidates.

Auto-detected formats: email, uri, date-time, ipv4, ipv6, uuid, hostname. Output: Complete JSON Schema with $schema, type, properties, required, format annotations, and description placeholders.
