## Which one, for what

### Apideck Accounting API + MCP (BB)

Good for: A SaaS product that has to reach many customers' ledgers, especially European or desktop ones, through one agent-friendly MCP.

Ahead on:
- Reliability, 75 against 44
- Schema & documentation, 92 against 51
- Agent ergonomics, 88 against 67
- Security & auth, 66 against 61
- Payments & pricing, 30 against 22
- Maintenance & community, 80 against 73

Also in its favour:
- Agent-ready, a grade of BB or better
- A hosted endpoint, with nothing to install
- Runs on your own machine
- Free to start without a card

Watch for: No published rate limits of Apideck's own, only connector limits mirrored in headers

### Odoo External API (C)

Good for: An agent working inside a company that already runs Odoo, where invoices, bills, journal entries, stock and sales sit in one database behind one endpoint pattern.

Ahead on:
- Transparency & trust, 93 against 73

Also in its favour:
- Open source

Watch for: On Odoo Online the external API is limited to the Custom plan. One App Free and Standard exclude it

## Verdicts

**Apideck Accounting API + MCP.** 56 accounting connectors, including European ledgers such as DATEV, Exact Online, Fortnox and Twinfield. No published rate limits of Apideck's own, only connector limits mirrored in headers.

**Odoo External API.** One endpoint pattern reaches every model, with field selection, filters and paging, and keys that expire within three months. On Odoo Online the external API needs the Custom plan, there is no OpenAPI file, and the acceptable use policy asks for about one call a second with no parallel calls.

## Before you call either

### Apideck Accounting API + MCP

1. Stay in dynamic mode and search for tools. Static mode loads all 362 schemas
2. Start the MCP with --lock-identity (or ?lock_identity=true) when one agent serves one customer
3. Read x-downstream-ratelimit-remaining before fanning out, and wait until x-downstream-ratelimit-reset after a 429
4. List before you retry a create that timed out. Writes aren't idempotent and there's no idempotency key
5. Pass fields= on list calls to cut the response to the columns you need

### Odoo External API

1. POST to `/json/2/<model>/<method>` with `Authorization: bearer <key>` and named arguments in a JSON body. Add `X-Odoo-Database` when one host serves several databases
2. Pass `fields` and `limit` on `search_read`. The default limit is every matching record
3. Create invoices and bills on `account.move` with `move_type` set to `out_invoice` or `in_invoice`, then call `action_post`. A new move is a draft
4. Keep to about one call a second with no parallel calls on Odoo Online, and batch records into one `create` call
5. Ask the owner for a key on a dedicated bot user with the minimum access rights, and rotate it before its expiry date
