Advanced MCP Server Integration - Taking Your Cursor Experience to the Next Level

After setting up the basic MCP proxy for running npx-based MCP servers with Cursor, there are several advanced techniques and optimizations that can further enhance your development workflow. This post explores the next steps in MCP server integration.

Automating MCP Proxy Startup with Tilt​

In the previous post, we covered how to manually run the MCP proxy. Now let's automate this process using Tilt:

# MCP Proxy for Kubernetes
local_resource(
    'mcp-proxy-k8s',
    serve_cmd='mcp-proxy --sse-port 7070 --pass-environment npx -- mcp-server-kubernetes',
    labels=['mcp', 'tools'],
    allow_parallel=True
)

By adding this to your Tiltfile, the MCP proxy will automatically start whenever you run tilt up.

Running Multiple MCP Servers Simultaneously​

For complex development environments, you might need multiple MCP servers running at once. Here's how to configure them with different ports:

# First MCP server (Kubernetes)
mcp-proxy --sse-port 7070 --pass-environment npx -- mcp-server-kubernetes

# Second MCP server (Redis)
mcp-proxy --sse-port 7071 --pass-environment npx -- mcp-server-redis

# Third MCP server (SQL)
mcp-proxy --sse-port 7072 --pass-environment npx -- mcp-server-sql

Then in Cursor, add each server with its respective port in your .cursor/mcp.json file:

{
  "mcp-k8s-proxy": {
    "url": "http://localhost:7070"
  },
  "mcp-redis-proxy": {
    "url": "http://localhost:7071"
  },
  "mcp-sql-proxy": {
    "url": "http://localhost:7072"
  }
}

Exploring Available MCP Servers​

There's a growing ecosystem of MCP servers that can enhance your development workflow. Here are some interesting ones to explore:

Search and Information Retrieval​

  • Brave Search - Web and local search using Brave's Search API

Monitoring and Visualization​

  • Grafana MCP - Integrate Grafana dashboards with Cursor

Task Management​

Social Media Integration​

Utilities​

Creating Custom MCP Servers​

For our Mercury TA API, we'll use FastMCP to quickly create a custom MCP server. This will allow us to expose our technical analysis capabilities directly to Cursor.

The TypeScript SDK is also available for creating custom servers:

Exploring MCP Platforms​

Some platforms provide hosted MCP servers and additional tools:

Future Explorations​

Topics we'll investigate in future posts:

  • Does Ollama have any support for MCP (possibly via tooling)?

Debugging MCP Communication​

One of the most valuable tools for working with MCP servers is the MCP Inspector. This official tool allows you to:

  • Monitor and debug communication between Cursor and your MCP servers
  • Visualize the request/response flow
  • Test MCP servers directly without going through Cursor
  • Validate that your servers are working correctly

The Inspector is essential when developing custom MCP servers or troubleshooting connection issues. It provides visibility into what's happening behind the scenes, making it much easier to identify and fix problems.

To use the Inspector:

# Install the MCP Inspector
npm install -g @modelcontextprotocol/inspector

# Run the Inspector
mcp-inspector

Then open your browser to the provided URL (typically http://localhost:3000) to access the Inspector interface.
