No official MCP server, OpenAPI spec or llms.txt.\n\n**Nutshell.** The REST reference is served as Markdown with an OpenAPI fragment per operation, and the hosted MCP server uses OAuth with PKCE and can only read. No rate limit numbers, error format or API changelog were found in the reviewed documentation, and API keys carry no scopes.\n\n## Before you call either\n\n### Copper API\n\n1. Send `X-PW-AccessToken`, `X-PW-Application: developer_api` and `X-PW-UserEmail` on every call, or it fails\n2. Set `page_size` to 200 and stop when a page comes back short, since `X-PW-TOTAL` is only an upper bound\n3. Back off on 429 on your own clock, since no Retry-After is documented\n4. Narrow searches that would pass 100,000 records, which is where results stop\n5. Read connect fields before you update a record, because an update that omits them can delete connections\n\n### Nutshell\n\n1. Authenticate REST calls with HTTP Basic, a Nutshell user's email as username and the API key as password, against `https://app.nutshell.com/rest`\n2. Use IDs in the `\u003cnumber\u003e-\u003ctype\u003e` form, such as `3-accounts`, and send updates as JSON Patch with `content-type: application/json-patch+json`\n3. Page lists with `page[limit]` and `page[page]`, which is 0-based, and call `/accounts/list/fields` or the lead and contact equivalents for valid filter keys\n4. Use the REST API for writes. The MCP server only reads, and OAuth tokens need the `read` scope\n5. Filter webhook events yourself, because every webhook receives all events and subscriptions are created in Setup, not through the API\n\n## Questions\n\n### Which is better for AI agents, Copper API or Nutshell?\n\nNutshell scores 49.6 (D) on agent readiness against Copper API's 46.7 (D), and leads in 5 of 7 scored categories. Copper API leads on reliability.\n\n### Do Copper API and Nutshell need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Copper API and Nutshell without installing anything?\n\nYes.
