Overview

What is Perplexity Web Search MCP Server?

Perplexity Web Search MCP Server is a simple MCP (Model Context Protocol) server that provides web search functionality using the Perplexity API. It allows Claude or other MCP-compatible AI assistants to search the web and get up‑to‑date information with sources and citations.

Finally, configure your Claude Desktop client by adding the server to its claude_desktop_config.json with the correct command and path.

Frequently asked questions

1

What API key is required?

You need a Perplexity API key, which you can generate at [Perplexity API Settings](https://www.perplexity.ai/settings/api) after creating an account.

2

How do I filter search results by time period?

Use the `recency` parameter in the `search_web` tool or the `--recency` flag in the test script. Accepted values are `day`, `week`, `month` (default), and `year`.

3

How can I test the server without running the full MCP setup?

Run the included test script: `python test_server.py "your query here" --recency month`. It will output results directly to the console.

4

What runtime dependencies are required?

The server requires Python and the packages installed via `pip install -e .` (or with `uv`). There is no additional runtime beyond the Perplexity API key.

5

How do I configure the server for use with Claude Desktop?

Edit your Claude Desktop configuration file (macOS: `~/Library/Application Support/Claude/claude_desktop_config.json`; Windows: `%APPDATA%/Claude/claude_desktop_config.json`) and add the server definition with the `command` set to `python` and `args` pointing to the full path of `server.py`. Also set the `PERPLEXITY_API_KEY` in the `env` field.
