import_spec
shallowio.github.fetchsandbox/mcp · Verify this server
Ingest an OpenAPI spec and get a working sandbox you can call immediately. REQUIRED: pass EITHER `url` OR `content` — never just `name` alone (name is a display label, not a lookup). If the user mentions a popular API by name (Stripe, GitHub, Twilio, Notion, OpenAI, etc.), FIRST call `list_specs` with a filter to confirm it's in the catalog, then call import_spec with that vendor's public OpenAPI URL (e.g. Stripe: https://raw.githubusercontent.com/stripe/openapi/master/openapi/spec3.json). The backend content-hashes the spec and auto-matches to the bundled sandbox when applicable. Returns sandbox_id, workflows_preview, and a base_url that proxies schema-validated responses. Private URLs (localhost, 10.x, 192.168.x) are rejected by the backend — use `content` to paste those inline.
