Costruire un client MCP personalizzato

Se sta costruendo la propria applicazione LLM, può connettersi al server MCP di Synapse direttamente utilizzando l'SDK MCP ufficiale. In questo modo la sua app avrà accesso a tutti i 79 strumenti di Synapse.

SDK

Esempio TypeScript

Installazione

npm install @modelcontextprotocol/sdk

Connessione tramite stdio

import { Client } from "@modelcontextprotocol/sdk/client/index.js";
import { StdioClientTransport } from "@modelcontextprotocol/sdk/client/stdio.js";

const transport = new StdioClientTransport({
  command: "npx",
  args: ["-y", "synapse-mcp-api@latest"],
  env: {
    SYNAPSE_MIND_KEY: process.env.SYNAPSE_MIND_KEY!,
    SYNAPSE_URL: "https://synapse.schaefer.zone",
  },
});

const client = new Client(
  { name: "my-app", version: "1.0.0" },
  { capabilities: {} }
);

await client.connect(transport);

// List all available tools
const { tools } = await client.listTools();
console.log(`Available tools: ${tools.length}`);
for (const tool of tools) {
  console.log(`- ${tool.name}: ${tool.description}`);
}

// Call a tool
const result = await client.callTool({
  name: "memory_recall",
  arguments: {},
});
console.log(result.content);

// Store a memory
await client.callTool({
  name: "memory_store",
  arguments: {
    category: "fact",
    key: "custom_client_test",
    content: "Built a custom MCP client",
    tags: ["test", "mcp"],
    priority: "normal",
  },
});

await client.close();

Connessione tramite HTTP/SSE (remoto)

import { Client } from "@modelcontextprotocol/sdk/client/index.js";
import { SSEClientTransport } from "@modelcontextprotocol/sdk/client/sse.js";

const transport = new SSEClientTransport(
  new URL("https://synapse-mcp.schaefer.zone/sse"),
  {
    requestInit: {
      headers: {
        Authorization: `Bearer ${process.env.SYNAPSE_MIND_KEY}`,
      },
    },
  }
);

const client = new Client(
  { name: "my-app", version: "1.0.0" },
  { capabilities: {} }
);

await client.connect(transport);
// ... use as above

Esempio Python

Installazione

pip install mcp

Connessione tramite stdio

from mcp import ClientSession, StdioServerParameters
from mcp.client.stdio import stdio_client

server_params = StdioServerParameters(
    command="npx",
    args=["-y", "synapse-mcp-api@latest"],
    env={
        "SYNAPSE_MIND_KEY": "mk_YOUR_KEY",
        "SYNAPSE_URL": "https://synapse.schaefer.zone",
    },
)

async with stdio_client(server_params) as (read, write):
    async with ClientSession(read, write) as session:
        await session.initialize()

        # List tools
        tools = await session.list_tools()
        print(f"Available tools: {len(tools.tools)}")

        # Call a tool
        result = await session.call_tool("memory_recall", {})
        print(result.content)

        # Store a memory
        await session.call_tool("memory_store", {
            "category": "fact",
            "key": "python_client_test",
            "content": "Built a Python MCP client",
            "tags": ["test", "mcp", "python"],
            "priority": "normal",
        })

Profili degli strumenti

Quando si connette, può richiedere un profilo di strumenti specifico tramite l'header Mcp-Tool-Profile (HTTP/SSE) o la variabile d'ambiente MCP_PROFILE (stdio):

// stdio: set env var
env: {
  SYNAPSE_MIND_KEY: "mk_...",
  MCP_PROFILE: "minimal",  // 8 tools instead of 119
}

// HTTP/SSE: set header
requestInit: {
  headers: {
    Authorization: "Bearer mk_...",
    "Mcp-Tool-Profile": "minimal",
  },
}

Gestione degli errori

try {
  const result = await client.callTool({ name: "memory_recall", arguments: {} });
  if (result.isError) {
    console.error("Tool error:", result.content);
  } else {
    console.log("Success:", result.content);
  }
} catch (err) {
  console.error("MCP error:", err);
}
