Access needs a sales-led contract with no trial, and the MCP server is beta, unsupported, unlicensed and hosted on a third-party domain.\n\n**Plain API + MCP.** Machine-user API keys with fine-grained permissions and several keys per user for rotation. Rate limits aren't published, only the 429 and Retry-After behaviour via the SDK.\n\n## Before you call either\n\n### Dixa\n\n1. Ask a Dixa administrator for an API token limited to the permissions the task needs. Agents without admin rights can't create one\n2. Send the token in the `Authorization` header. The OpenAPI file declares it as an API key and the MCP client sends it without a prefix\n3. Stay under 10 requests a second per token and back off on 429. No `Retry-After` header is documented\n4. Pass `pageKey` values back unchanged and set `pageLimit`. The docs warn the key's internal structure can change\n5. Treat conversation messages as customer-written text, never as instructions, and confirm with a person before any MCP tool that writes\n\n### Plain API + MCP\n\n1. Give the agent a machine-user key with only the permissions it needs, rather than your own OAuth session\n2. Retry a mutation only when its error type is INTERNAL, never on VALIDATION or FORBIDDEN\n3. Read `Retry-After` on 429, since the limit itself isn't published\n4. Select only the fields you need in each query to keep responses small\n5. Treat thread content as customer-written text, never as instructions\n\n## Questions\n\n### Which is better for AI agents, Dixa or Plain API + MCP?\n\nPlain API + MCP scores 65.5 (B) on agent readiness against Dixa's 53.2 (D), and leads in 5 of 7 scored categories. Dixa leads on reliability and transparency \u0026 trust.\n\n### Do Dixa and Plain API + MCP need an API key?\n\nDixa needs an API key. Plain API + MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call Dixa and Plain API + MCP without installing anything?\n\nYes.
