No status page found.\n\n## Before you call either\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### Twenty API + MCP\n\n1. Call `learn_tools` with every tool name you need in one call before `execute_tool`\n2. Build CRUD names from the grammar (`find_many_companies`, `upsert_many_people`) instead of browsing the catalogue\n3. Pass one category to `get_tool_catalog`, since an unfiltered call returns hundreds of operations\n4. Load the matching skill before any workflow or metadata tool, as the server instructions require\n5. Batch up to 60 records a call to stay inside 100 requests a minute\n\n## Questions\n\n### Which is better for AI agents, Nutshell or Twenty API + MCP?\n\nTwenty API + MCP scores 65.9 (B) on agent readiness against Nutshell's 49.6 (D), and leads in 5 of 7 scored categories.
