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:

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

Connector Fails to Start

Symptoms: Status remains "Inactive" or shows error, Red dot indicator

Cause: Command not found or missing dependencies in the environment.

Solution:

  • Test the command in a regular terminal window to ensure it works.
  • Use absolute paths for all executables (e.g., use /opt/homebrew/bin/node instead of node).
  • Check if the server requires specific environment variables.

Permission Errors

Symptoms: "Access denied" responses, Server crashes on file access

Cause: macOS permissions blocking access to specific folders.

Solution:

  • Ensure Perplexity (or the terminal running the server) has Full Disk Access in macOS System Settings if accessing sensitive directories.
  • Verify PerplexityXPC is correctly installed.

Tools Not Visible

Symptoms: Perplexity does not attempt to use the tool, Hallucinated responses

Cause: Connector not selected as a source.

Solution:

  • Start a NEW thread.
  • Explicitly select the connector in the "Sources" menu before sending the prompt.

Perplexity MCP Server not appearing in Perplexity

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

  • Verify configuration syntax
  • Check Perplexity MCP Server installation
  • Restart Perplexity
  • Check logs for error messages
