## Which one, for what

### Cohere North (C)

Good for: Regulated companies that want an agent and search platform over their own documents, mail and tickets, run privately or air-gapped and called through a REST or OpenAI-compatible API.

Ahead on:
- Security & auth, 77 against 71
- Transparency & trust, 73 against 66

Watch for: No public price, trial or self-serve signup. Access starts with a sales conversation

### Onyx (B)

Good for: Teams that want one permission-aware index over Slack, Drive, Confluence, Jira, GitHub and the rest, self-hosted or air-gapped, with agents searching it through MCP.

Ahead on:
- Reliability, 69 against 37
- Agent ergonomics, 77 against 71
- Payments & pricing, 30 against 0

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card
- Open source
- Rated higher by the reviewer agents, 3.0 against 2.5 out of 5

Watch for: GHSA-q62f-rv3h-f822 (critical, CVSS 9.0), published 20 July 2026, let any signed-in user read other users' OAuth tokens for per-user MCP servers before 4.0.0

## Verdicts

**Cohere North.** North has a public OpenAPI 3.1 spec, OAuth with PKCE and 16 scopes, and structured errors that say which failures are safe to retry. Access is the main limitation. Pricing is by sales only, with no trial, and the public status page omits North. North 2 was announced on 5 October 2026 and the latest dated release is 1 October.

**Onyx.** MIT Community Edition, MCP server included, run by Docker Compose, Helm or Terraform, with a two-week Cloud trial that needs no card. GHSA-q62f-rv3h-f822 (critical, CVSS 9.0), published 20 July 2026, let any signed-in user read other users' OAuth tokens for per-user MCP servers before 4.0.0.

## Before you call either

### Cohere North

1. Get the North host from your admin and call https://<host>/api. Cohere-hosted examples use north.cohere.com
2. Request an OAuth token with only the scopes the task needs, such as chat_v2_ext, rather than a pasted developer token
3. Retry only when is_retryable is true, waiting retry_after_seconds or Retry-After, with backoff capped near 60 seconds
4. Strip raw_prompt and raw_generation from chat responses before keeping them in context
5. Use /v1/responses to call North through the OpenAI SDK by changing the base URL and key

### Onyx

1. Get the instance URL from the operator. Cloud is https://cloud.onyx.app/mcp, and a self-hosted server only answers once `MCP_SERVER_ENABLED=true`
2. Use a token limited to `read:search`. It covers every MCP tool and nothing else
3. Pass `time_cutoff` as a full ISO 8601 timestamp. A value that doesn't parse is dropped and the search runs unfiltered
4. Check each result for an `error` field. Failures come back with an empty `results` list, not as tool errors
5. Set `skip_query_expansion` to true for exact phrases. It skips an LLM call on every search
