The problem
Useful context is split across three apps. Switching tabs breaks every train of thought.
The outcome
Inside Claude Desktop, ask 'what did we decide about pricing last week?' — answer pulls from all three, cited.

How it works
Implements an MCP server with three tools: `search_notion`, `search_linear`, `search_slack`. Bind once in Claude Desktop, search everything from chat.
Step 1
1 — MCP server scaffold
Use `@modelcontextprotocol/sdk`. One process exposes all three tools.
server.ts
import { Server } from "@modelcontextprotocol/sdk/server/index.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
const server = new Server({ name: "internal-search", version: "1.0.0" }, { capabilities: { tools: {} } });
server.tool("search_notion", { query: z.string() }, async ({ query }) => ({ content: [{ type: "text", text: await notionSearch(query) }] }));
server.tool("search_linear", { query: z.string() }, async ({ query }) => ({ content: [{ type: "text", text: await linearSearch(query) }] }));
server.tool("search_slack", { query: z.string() }, async ({ query }) => ({ content: [{ type: "text", text: await slackSearch(query) }] }));
await server.connect(new StdioServerTransport());Step 2
2 — Bind in Claude Desktop
Secrets resolve from the locker — never paste tokens into the config file.
claude_desktop_config.json
{
"mcpServers": {
"internal-search": {
"command": "node",
"args": ["./dist/server.js"],
"env": { "NOTION_TOKEN": "${NOTION_TOKEN}", "LINEAR_API_KEY": "${LINEAR_API_KEY}", "SLACK_BOT_TOKEN": "${SLACK_BOT_TOKEN}" }
}
}
}One-line deploy
The button above runs the same command with your saved config. This is the raw CLI form.
