Parallel Search MCP

Installation

Use the default remote endpoint at https://search.parallel.ai/mcp for anonymous access.

For clients that need enforced authentication or OAuth, use https://search.parallel.ai/mcp-oauth instead.

Configuration

The default endpoint is free to use without an API key. To unlock higher rate limits, pass a Parallel API key as a Bearer token in the Authorization header.

Capabilities

• web_search: general-purpose web search for current information and diverse sources
• web_fetch: token-efficient markdown extraction from specific URLs

Limitations

• The default /mcp endpoint does not advertise OAuth
• Search runs in basic mode for low-latency agent use
• Output excerpts per call are capped to roughly 25,000 characters
• Use /mcp-oauth when you need OAuth sign-in or organization-enforced authentication
