How do I install Openapi or Sdk in Claude Desktop or Cursor?

Copy the mcpServers JSON configuration snippet provided on this page into your claude_desktop_config.json or ~/.cursor/mcp.json file and restart your AI client.

Are Openapi and Sdk free or paid?

Openapi operates under a Free / Open Source model (No auth required). Sdk operates under a BYOK (Pay Provider Direct) model (API Key required).

Which MCP server has more tools and community activity?

Openapi lists 0 tools with 1 views and 3 GitHub stars. Sdk lists 578 tools with 4 views and 7 GitHub stars.

Can I use both Openapi and Sdk together in the same MCP host?

Yes! MCP hosts like Claude Desktop, Cursor, Windsurf, Cline, and VS Code support configuring multiple servers under the mcpServers object simultaneously.

How do I install Openapi or Sdk in Claude Desktop, Cursor, or Windsurf?

Both servers follow the standard Model Context Protocol configuration format. Simply copy the JSON block from the configuration section above and paste it into your AI client's mcpServers configuration object (for instance in claude_desktop_config.json or ~/.cursor/mcp.json ), then completely restart or refresh the application.

Are Openapi and Sdk free to use, or do they require API keys?

Openapi is listed under a Free / Open Source model with No auth required . Sdk operates under a BYOK (Pay Provider Direct) model with API Key required . If environment variables are required (such as API keys), be sure to define them under the env key in your MCP client's configuration file.

Can I run both Openapi and Sdk at the same time in my AI client?

Yes! MCP clients support multi-server orchestration. You can include both openapi and 2s-io-sdk as distinct keys inside the single mcpServers object in your configuration file. Your AI assistant will automatically select and call the appropriate tool from either server during chat sessions.

No explicit tool names declared in metadata yet. Check project README on main listing page.

Sdk Tools (578)

search.endpoints

Find the right 2s endpoint(s) for a task using a natural-language query (e.g. "screen a company for sanctions", "decode a VIN", "check a domain's email security"). Returns ranked matches with id, path, method, price, and description. Use this to discover capabilities before calling.

batch.run

Run up to 50 endpoint calls behind ONE x402 payment. Price = exact sum of the sub-call prices (no discount). Atomic: every sub-call must succeed or nothing is charged (failures are returned so you can retry for free). Sub-calls must be ordinary catalog endpoints (no bearer-only, deprecated, variable-priced, or metered-upstream endpoints; no nested batch). Each item carries that endpoint's own response in `data`.

soil.profile

Ground-truth soil profile for any US lat/lng from USDA-NRCS SSURGO. Returns the soil map unit + component soil types ranked by composition %, each with taxonomic order/class, drainage class, hydrologic group, and slope. Keyless, public-domain. For agronomy, land/septic/foundation suitability, hydrology, crop-fit. Water/unsurveyed points return an empty component list.
