Parallel

Parallel provides hosted MCP tools for web search and URL fetching.

Setup

Add the parallel_search capability to an agent or harness. It works for free without any connection.

To use a Parallel API key, add a Parallel connection in Settings > Connections, then configure the capability with auth: "connection".

To use Parallel’s OAuth-compatible MCP endpoint, configure the capability with endpoint: "oauth". This mode requires the Parallel connection because the endpoint rejects anonymous requests.

Tools

Tool	Purpose
`mcp_parallel__web_search`	Search the web and return ranked URLs with excerpts.
`mcp_parallel__web_fetch`	Fetch and extract focused content from known URLs.

Agents should reuse one stable session_id across Parallel tool calls in the same conversation.
