# Stainless: MCP vendor profile

Stainless generates an MCP server from an OpenAPI spec as a subpackage of a generated TypeScript SDK, exposing a code execution tool and a docs search tool instead of one tool per endpoint, as documented by the vendor. Stainless pricing counts a "generator" as any single SDK, docs site or MCP server (www.stainless.com).

## At a glance

| Type | SDKs and frameworks |

| Price | per generator |
| Read | 5 November 2026 |

## What it does for this layer

Stainless-hosted code execution (stainless-sandbox mode) is deprecated, and the tool may return 410 Gone, in which case the docs say to run with --code-execution-mode=local ([www.stainless.com](https://www.stainless.com/docs/mcp)). Stainless runs an MCP Portal page with guides and a customer story about Scorecard's remote MCP server, built with Stainless and Clerk ([www.stainless.com](https://www.stainless.com/mcp)). Stainless generates MCP servers from an OpenAPI specification; the docs say "MCP server generation is experimental" ([www.stainless.com](https://www.stainless.com/docs/mcp)).

A Stainless MCP server is generated as a subpackage of the TypeScript SDK at packages/mcp-server, enabled by adding mcp\_server options to the typescript target ([www.stainless.com](https://www.stainless.com/docs/mcp)). The Stainless code execution tool accepts TypeScript that runs against the generated SDK, and --code-execution-mode=local runs it in a Deno subprocess ([www.stainless.com](https://www.stainless.com/docs/mcp)).
