parallel-web/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 in Cursor · Install in VS Code · Manual setup · Documentation
Manual setup
Choose your client. You only need one of these options.
Codex
Start a new Codex session and run /mcp to check the connection. See the Codex MCP guide for configuration options.
Gemini CLI
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. It's available in the Hermes plugin catalog. Install and enable it with:
Start a new session so Hermes loads the enabled package. Ask Hermes to use the Parallel MCP web_search tool to find official documentation, then web_fetch 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:
Restart OpenCode and run opencode mcp list to check the connection. See the OpenCode MCP guide for details.
OpenClaw
Follow the OpenClaw setup guide to install the Parallel plugin, then set tools.web.search.provider to parallel-free. No Parallel account or API key is needed.
Cursor, VS Code, and other clients
Use this remote MCP server URL:
Select HTTP or Streamable HTTP if your client asks for a transport. Follow the client-specific instructions for the right settings file and format.
Try it
Ask your agent:
> Use Parallel to find the official FastAPI docs for response models. Show me a small example and link to the source.
Or try:
> Use Parallel to check the latest stable Node.js release and its release notes. Cite the official sources.
> Use Parallel to read https://modelcontextprotocol.io/introduction and explain how MCP connects an agent to tools.
Your agent can use two tools:
| Tool | What it does |
| --- | --- |
| web_search | Searches the web and returns relevant excerpts with source links. |
| web_fetch | Reads specific URLs and returns page content for your agent to use. |
Search results often contain enough information to answer. Your agent can fetch a page when it needs more detail.
Free access and higher limits
This plugin is anonymous by design: both tools work with no account, API key, or login, subject to free-tier rate limits. The free tier is intended for personal agents, hobby projects, and exploration.
