Building AI agents often starts with installing bloated orchestration frameworks that obscure what's actually happening under the hood. But Anthropic's Model Context Protocol (MCP) standardizes tool integration into clean JSON-RPC 2.0.

In this tutorial, we will build a minimal, local-first agent client using only Python's standard library (`json`, `subprocess`, `os`), connected to structured MCP server schemas.

Instead of writing custom code for every tool:

Rather than browsing static websites, we use a structured JSON schema:

```
json
{
  "id": "mcp-free-01",
  "name": "SQLite & Local File MCP",
  "category": "Database & Storage",
  "protocol": "Model Context Protocol (JSON-RPC 2.0)",
  "input_schema_summary": "{\"query\": \"string (SQL)\"}"
}
Step 2: Zero-Dependency Client
​Here is the minimal runner:

import json

class MinimalMCPClient:
    def __init__(self, catalog_path):
        with open(catalog_path, 'r', encoding='utf-8') as f:
            self.catalog = json.load(f)

    def execute(self, tool_id: str, args: dict):
        tool = next((t for t in self.catalog if t["id"] == tool_id), None)
        if not tool:
            raise ValueError(f"Tool {tool_id} not found")
        return {"status": "success", "tool": tool["name"], "args": args}
