The last release was 23 June 2026, the `@karrio/mcp` package the docs install is absent from npm, and `api.karrio.io` didn't resolve on 8 October 2026.\n\n**Sendcloud.** API v3 has 29 public OpenAPI 3.1 specs, an llms.txt index, a dated changelog and a hosted MCP server with toolset filtering. OAuth has one scope, `api`, so a credential can't be limited to reading. The changelog records response fields removed from tracking events on 25 September 2026 with no earlier deprecation entry.\n\n## Before you call either\n\n### Karrio\n\n1. Run your own instance with Docker Compose and call it at `http://localhost:5002`. Don't rely on `api.karrio.io`, which didn't resolve on 8 October 2026\n2. Don't run `npx karrio-mcp` or `npx -y @karrio/mcp`. Neither name is published on npm, so build the server from `packages/mcp` in the repository\n3. Change the default `admin@example.com` and `demo` login before the instance is reachable, and upgrade to 2026.1.32 or later so passwords aren't stored as MD5\n4. Don't blind-retry `POST /v1/shipments` with a `service` set or `POST /v1/shipments/{id}/purchase`. Fetch the shipment and check its status first, since no idempotency key exists\n5. Use a test-mode API key while building. Send it as the HTTP Basic username or as `Authorization: Token key_...`\n\n### Sendcloud\n\n1. Use API v3 at https://panel.sendcloud.sc/api/v3. The v2 create-parcel endpoint is closed to accounts created from April 2026\n2. Test with `shipping_option_code` `sendcloud:letter` (returns use `sendcloud:letterreturn`). Any other label is billed unless cancelled within the carrier's deadline\n3. Set `external_reference_id` on every shipment so a retry returns the existing shipment (409) instead of a second label\n4. Read the `errors` array on synchronous announce responses. A carrier failure can arrive inside a success status\n5. Connect MCP with `?toolsets=shipments,shipping-options,parcel-tracking,returns` to keep the tool list short. Create and cancel tools act on the live account\n\n## Questions\n\n### Which is better for AI agents, Karrio or Sendcloud?\n\nSendcloud scores 62 (B) on agent readiness against Karrio's 48.7 (D), and leads in 5 of 7 scored categories. Karrio leads on reliability.\n\n### Do Karrio and Sendcloud need an API key?\n\nKarrio needs an API key. Sendcloud takes an API key or an OAuth sign-in.\n\n### Can an agent call Karrio and Sendcloud without installing anything?\n\nNo hosted endpoint is listed for Karrio. Sendcloud has a hosted endpoint at https://mcp.sendcloud.com/mcp.\n\n### Are Karrio and Sendcloud open source?\n\nKarrio is open source (LGPL-3.0 for the server, SDK and modules. Code under `ee/` is under the Karrio Enterprise licence and needs a subscription for production use. The MCP package in `packages/mcp` is Apache-2.0). No open-source release is listed for Sendcloud.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/karrio-vs-sendcloud.json, and with the fewest tokens: https://www.anchorterminal.com/compare/karrio-vs-sendcloud.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"karrio\", \"b\": \"sendcloud\"}`.
