Your client discovers the enabled tools and their current arguments when it connects. Hosted defaults, account permissions and optional scrape or research calls can change the result and bill. ## Connect a web search API to your AI agent with MCP Choose the example for your client and provider. Remote-capable clients accept a server URL; local STDIO clients launch a process. The examples below follow the linked vendor guides. Configuration formats vary by client. ### Exa: hosted, keyless search A Cursor-style remote configuration for Exa’s rate-limited keyless connection. OAuth and API-key options are in the official guide. View MCP configuration `{ "mcpServers": { "exa": { "url": "https://mcp.exa.ai/mcp" } } }` [Official setup instructions ↗](https://exa.ai/docs/get-started/exa-mcp) ### Perplexity: local server with an API key A Claude Desktop-style local configuration. Replace the placeholder through your client’s configuration or secret settings. Select perplexity\_search for ranked search results. View MCP configuration `{ "mcpServers": { "perplexity": { "command": "npx", "args": [ "-y", "@perplexity-ai/mcp-server" ], "env": { "PERPLEXITY_API_KEY": "YOUR_PERPLEXITY_API_KEY" } } } }` [Official setup instructions ↗](https://github.com/perplexityai/modelcontextprotocol) ### Brave: local search tools Run the official Brave server over STDIO in a compatible local client. Supply your own Brave API key and choose the search surface your application needs. View MCP configuration `{ "mcpServers": { "brave-search": { "command": "npx", "args": [ "-y", "@brave/brave-search-mcp-server", "--transport", "stdio" ], "env": { "BRAVE_API_KEY": "YOUR_BRAVE_API_KEY" } } } }` [Official setup instructions ↗](https://github.com/brave/brave-search-mcp-server) ### Check the first search after connecting Enable the chosen search tool and ask: “Find the official documentation for this API feature and return the source URLs with the relevant passages.” Inspect the selected tool, query and sources. For a fair comparison, repeat the same questions with the same agent, result budget and search mode, and record accuracy, search time and total usage. ## Benchmark method and source data Task completion on 100 developer questions with the same agent using search results. Each task requires a passing patch and a citation from the run's sources. Search latency and total task latency are shown separately. Each row is one measured configuration. Missing measurements appear as a dash. Scores and timings measure the underlying search APIs in our developer-agent benchmark. MCP connection options and tools are verified against vendor documentation; MCP transport overhead and client tool selection require a separate end-to-end test.
