Perplexity MCP Server + OpenCode: Complete MCP Integration

Perplexity MCP Server is a MCP server that The official MCP server implementation for Perplexity API Platform. Provides real-time web search, deep research, and advanced reasoning capabilities through Sonar AI models and the Search API..

When integrated with OpenCode, you can:

  • Direct web search using Perplexity Search API with ranked results
  • General-purpose AI with real-time web integration for everyday questions
  • Comprehensive research with thorough analysis and citations

This guide provides step-by-step instructions to set up Perplexity MCP Server in OpenCode, including configuration, examples, and troubleshooting.

What You'll Achieve

After completing this setup:

  • Perplexity MCP Server will be fully integrated and operational
  • You can use Perplexity MCP Server tools directly in OpenCode
  • All Perplexity MCP Server capabilities will be available for your workflows
  • Access to 4 different tools

Prerequisites

Before starting, ensure you have:

  • Node.js 18+
  • npm or npx
  • Perplexity API key
  • Your Perplexity API key for authentication with Sonar models
  • OpenCode installed and configured
  • Compatible operating system (macOS, Linux, Windows)

Installation

Step 1: Install Perplexity MCP Server

Install using npm:

npx -y perplexity-mcp

Verify installation:

Server starts and connects to MCP client

Configuration

Step 2: Configure OpenCode

  1. Locate your configuration file:

  2. Add server configuration:

Configure MCP servers in your `opencode.json` or `opencode.jsonc`:

```json
{
  "mcp": {
    "my-mcp": {
      "type": "local",
      "command": ["npx", "-y", "@modelcontextprotocol/server-everything"],
      "environment": {
        "API_KEY": "$API_KEY"
      },
      "timeout": 5000
    },
    "remote-server": {
      "type": "remote",
      "url": "https://mcp.example.com/sse",
      "headers": {
        "Authorization": "Bearer $API_TOKEN"
      }
    }
  }
}

Disable a server temporarily:

{
  "mcp": {
    "my-mcp": {
      "type": "local",
      "command": ["npx", "-y", "mcp-server"],
      "enabled": false
    }
  }
}


3. **Restart OpenCode**

Completely quit and restart OpenCode to load the new configuration.



## Examples

Once configured, you can use Perplexity MCP Server in OpenCode:

### Real-Time Web Search

Search the web for current information and get ranked results

**Ask OpenCode:** "Search for the latest Model Context Protocol updates and announcements"

**Expected Result:** Ranked search results with titles, URLs, snippets, and metadata about MCP developments

### Quick Factual Queries

Get immediate answers to questions with web-backed accuracy

**Ask OpenCode:** "What are the system requirements for running Claude Desktop?"

**Expected Result:** Accurate, sourced answer with current system requirements and download links

### Deep Technical Research

Comprehensive analysis of complex technical topics

**Ask OpenCode:** "Research the differences between WebSocket, SSE, and HTTP polling for real-time applications"

**Expected Result:** Detailed comparison with citations, use cases, performance considerations, and recommendations

### Complex Problem Analysis

Advanced reasoning for technical decision-making

**Ask OpenCode:** "Analyze whether I should use Redis, Memcached, or PostgreSQL for caching in my Node.js application"

**Expected Result:** Step-by-step reasoning with trade-off analysis, benchmarks, and contextual recommendations



## Testing Your Setup

1. Run opencode in terminal
2. Add "use the mcp_name tool" to your prompts
3. Verify tool execution and response



## Troubleshooting

### Common Issues

#### API Key Invalid or Missing

**Symptoms:** 401 Unauthorized errors, Authentication failed messages, API key not found

**Cause:** PERPLEXITY_API_KEY environment variable not set or invalid

**Solution:**
- Verify API key is set: echo $PERPLEXITY_API_KEY
- Obtain valid key from https://www.perplexity.ai/account/api
- Ensure key is exported in shell: export PERPLEXITY_API_KEY="pplx-xxx"
- Check for typos or extra whitespace in key value

#### Connection Timeout

**Symptoms:** Request timeout errors, Server not responding, Long delays with no response

**Cause:** Network issues or timeout too short for deep research queries

**Solution:**
- Increase timeout: export PERPLEXITY_TIMEOUT_MS=900000
- Check internet connectivity
- Verify firewall allows outbound HTTPS to api.perplexity.ai
- For deep research, expect longer response times (2-5 minutes)

#### Proxy Configuration Errors

**Symptoms:** Connection refused, Proxy authentication failed, Network unreachable in corporate environment

**Cause:** Incorrect or missing proxy configuration for enterprise networks

**Solution:**
- Set proxy: export PERPLEXITY_PROXY=https://user:pass@proxy:port
- Alternative: export HTTPS_PROXY=https://proxy:port
- Verify proxy credentials are correct
- Contact IT if proxy blocks API requests

#### NPX Installation Fails

**Symptoms:** npx command not found, Package download errors, Permission denied

**Cause:** Node.js not installed or npm registry issues

**Solution:**
- Install Node.js 18+ from https://nodejs.org
- Clear npm cache: npm cache clean --force
- Try with explicit version: npx -y perplexity-mcp@latest
- Check npm registry connectivity

#### Strip Thinking Parameter Not Working

**Symptoms:** Response contains <think>...</think> tags, Excessive context token usage

**Cause:** strip_thinking parameter not passed correctly

**Solution:**
- Include strip_thinking: true in perplexity_reason calls
- This removes internal reasoning from responses
- Reduces token usage while preserving final answers

#### MCP Server Not Loading

**Symptoms:** Server not appearing in tools, Timeout errors, Command not found

**Cause:** Invalid configuration, missing dependencies, or timeout too short

**Solution:**
- Verify command array is correct in opencode.json
- Check environment variables are set properly
- Increase timeout value if server takes longer to start
- Test MCP server command independently in terminal

#### Context Limit Exceeded

**Symptoms:** Context too large errors, Slow responses, Truncated output

**Cause:** Too many MCP servers adding to context

**Solution:**
- Disable unused MCP servers with enabled: false
- Use per-agent tool configuration to limit active MCPs
- Avoid MCP servers that add many tokens (e.g., GitHub MCP)

#### Remote Server Connection Failed

**Symptoms:** Cannot connect to remote MCP, Authentication errors

**Cause:** Invalid URL, missing headers, or network issues

**Solution:**
- Verify remote server URL is correct
- Check authorization headers are properly configured
- Ensure environment variables for tokens are set

#### Perplexity MCP Server not appearing in OpenCode

**Symptoms:** Server not listed, Tools not available

**Cause:** Configuration or installation issue

**Solution:**
- Verify configuration syntax
- Check Perplexity MCP Server installation
- Restart OpenCode
- Check logs for error messages
