stepsearch

StepFun operates an official hosted remote MCP server, StepSearch — a search service built on the Model Context Protocol that gives Claude Code, Cline, OpenCode, Goose, and other MCP-compatible clients access to StepFun's web search and web fetch capabilities. It is an HTTP (streamable) remote server authenticated with the platform API key as a Bearer token; no local install is required. Tool list captured verbatim from the StepSearch documentation.

Connect

This is a remote MCP server — point an MCP client at the endpoint URL. Clients with native remote support (Claude, Cursor, VS Code, …):

# mcp client config (e.g. .mcp.json / mcp settings) { "mcpServers": { "stepfun": { "url": "https://api.stepfun.com/step_plan/v1/mcp/web_search/mcp" } } }

For stdio-only clients (older Claude Desktop, etc.), bridge with mcp-remote:

# Add to claude_desktop_config.json { "mcpServers": { "stepfun": { "command": "npx", "args": ["-y", "mcp-remote", "https://api.stepfun.com/step_plan/v1/mcp/web_search/mcp"] } } }

If the server requires authentication, add the provider's token/header (e.g. an X-API-Key) per its docs. A quick reachability check:

curl -i -X POST https://api.stepfun.com/step_plan/v1/mcp/web_search/mcp \ -H "Content-Type: application/json" -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Tools

web_search — Web-wide information retrieval with indexed results output.
web_fetch — Fetch a specified URL and extract its page content in structured form.

About MCP

The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.
