Parallel Search MCP server

Parallel Search MCP

Free web search for your coding agent.

Find current documentation, check facts, and read web pages without leaving your agent. No account or API key needed to get started.

Ask your agent to install

Copy this into your coding agent:

Install Parallel's free Search MCP in the coding agent I'm using now.
Identify your client and use its native MCP setup instructions:
https://docs.parallel.ai/integrations/mcp/search-mcp

Server name: parallel-search
Server URL: https://search.parallel.ai/mcp
Transport: Streamable HTTP
Authentication: none. No account, API key, or Parallel CLI is needed.

Preserve existing settings and reuse any connection to this endpoint.
Tell me if a restart or approval is required.

Once connected, check that web_search and web_fetch are available.
Use Parallel to find the official FastAPI response-model documentation
and return a source link. Report anything you couldn't verify.

Manual setup

Choose your client. You only need one of these options.

Codex

codex mcp add parallel-search --url https://search.parallel.ai/mcp

Start a new Codex session and run /mcp to check the connection. See the Codex MCP guide for configuration options.

Gemini CLI

gemini extensions install https://github.com/parallel-web/search-mcp

Restart Gemini CLI and run /mcp to check that parallel-search is connected. The extension uses Streamable HTTP and requires no Parallel account or API key. If you already configured parallel-search manually, that configuration takes precedence over the extension. See the extension guide for installation and update options.

Hermes Agent

Hermes already includes Parallel in its native web providers. Choose Parallel Free (keyless) in hermes tools to use that integration.

This optional package adds a direct connection to Parallel's MCP tools and the bundled setup skill. It leaves Hermes's native web-provider selection unchanged. We've submitted it to the Hermes plugin catalog, and approval is pending. Once it's listed, install and enable it with:

hermes plugins install parallel-search
hermes plugins enable parallel-search

Start a new session so Hermes loads the enabled package. Ask Hermes to use the Parallel MCP websearch tool to find official documentation, then webfetch to read a page. Use skills_list to discover the namespaced parallel-search-setup skill. No Parallel account, API key, or CLI is required.

Use either this package or a manually configured connection to https://search.parallel.ai/mcp to avoid duplicate MCP tools. Disable or remove the package with hermes plugins disable parallel-search or hermes plugins remove parallel-search. Update through hermes plugins update parallel-search; catalog updates use reviewed commit pins.

OpenCode

Merge this into your project's opencode.json:

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "parallel-search": {
      "type": "remote",
      "url": "https://search.parallel.ai/mcp",
      "oauth": false
    }
  }
}

Restart OpenCode and run opencode mcp list to check the connection. See the OpenCode MCP guide for details.
