JSON MCP

Schmiedeabzeichen

Der Model Context Protocol (MCP) -Server ermöglicht LLMs die effiziente Interaktion mit JSON-Dateien. Mit JSON MCP können Sie bestimmte Daten teilen , zusammenführen und suchen sowie JSON-Dateien anhand definierter Bedingungen validieren .

🌟 Hauptfunktionen

✅ Schnell und leicht
✅ LLM-freundliche Funktionalität

Related MCP server: mcp-server-test

🎥 Demo

Unten sehen Sie eine Demo, die die split -Funktionalität vorführt:

Demo: JSON aufteilen

🔧 Anwendungsfälle (Tools)

1. split

Teilen Sie eine JSON-Datei in eine angegebene Anzahl von Objekten auf.

Hinweis: Der Dateipfad muss angegeben werden.

Beispiel für eine Eingabeaufforderung:

Split JSON file from /Users/json-mcp/tests/merged.json
5 objects per file

2. merge

JSON-Dateien zu einer einzigen JSON-Datei zusammenführen

Hinweis: Der Ordnerpfad sollte angegeben werden

Beispiel für eine Eingabeaufforderung:

Merge json files from /Users/json-mcp/tests

⚙️ Konfiguration

Manuelle VS Code-Konfiguration

Um den JSON-MCP-Server manuell in VS Code zu konfigurieren, aktualisieren Sie die Datei „Benutzereinstellungen“ (JSON) :

{
  "mcp": {
    "servers": {
      "json-mcp-server": {
        "command": "npx",
        "args": ["json-mcp-server@latest"]
      }
    }
  }
}

Installation in VS Code

Sie können den JSON MCP-Server mithilfe der VS Code CLI installieren:

# For VS Code
code --add-mcp '{"name":"json-mcp-server","command":"npx","args": ["json-mcp-server@latest"]}'

Nach der Installation steht der JSON-MCP-Server zur Verwendung mit Ihrem GitHub Copilot-Agent in VS Code zur Verfügung.

TDQS

C2.6/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided. The description only says 'merge', without disclosing critical behaviors like conflict resolution, merge strategy (shallow vs deep), output location, or whether it modifies input files.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single short sentence, which is concise but sacrifices clarity. It is front-loaded but lacks necessary detail.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given one parameter, no output schema, and no annotations, the description is too incomplete. It does not explain merge behavior, input constraints, or output format, leaving significant gaps for an agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 0% description coverage for the 'path' parameter, and the description does not explain what 'path' represents. It could be a file path or directory; the ambiguity reduces usefulness.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool merges JSON files into one, with a verb 'merge' and resource 'JSON files'. It distinguishes from the sibling 'split' by being the opposite operation. However, it lacks specificity about what 'path' refers to (a single file? a directory?)

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. The sibling 'split' suggests a complementary tool, but no explicit when-to-use or when-not-to-use is given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS

B3.1/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description does not disclose side effects (e.g., whether the original file is modified or a new file created), required permissions, or other behavioral traits. With no annotations, the description carries the full burden but provides minimal info.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, no unnecessary words. However, the description could benefit from additional structure to cover key behavioral aspects.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with two parameters, the description is minimally adequate but leaves questions unanswered, such as output behavior and impact on input file. Missing details reduce completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, and the description adds no meaning beyond the schema. For example, 'path' and 'numObjects' are not detailed—no clarification on file format, location constraints, or how numObjects is applied.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (split) and the resource (JSON file). It distinguishes from the sibling tool 'merge' by implying opposite functionality.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives (e.g., 'merge'). No context about prerequisites or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

B3.3/5.0

Scored across 2 tools

Disambiguation5/5

Merge and split are clearly opposite operations. An agent can easily distinguish their purposes without ambiguity.

Naming Consistency5/5

Both tools use concise, single-word verbs (merge, split) following a consistent pattern.

Tool Count4/5

Two tools is slightly below the typical well-scoped range, but the server's narrow focus on merge/split operations justifies this minimal set.

Completeness4/5

The server covers the core merge and split operations for JSON files. Minor gaps like transform or validate exist, but the surface is complete for its stated purpose.
