## Which one, for what

### 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 40
- Schema & documentation, 88 against 9
- Agent ergonomics, 77 against 5
- Security & auth, 71 against 39
- Payments & pricing, 30 against 0
- Maintenance & community, 77 against 35
- Transparency & trust, 63 against 48

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 1.8 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

### Procore AI Go (F)

Good for: Field crews already on Procore with a Digital Coworker package who want spoken answers from project records on site.

Also in its favour:
- No incidents deducted, where Onyx loses 4 points for them

Watch for: No API, webhook or MCP tool an outside agent can use to ask Procore AI Go anything

## Verdicts

**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.

**Procore AI Go.** Procore AI Go lets crews on Procore's Digital Coworker packages ask spoken questions about drawings, RFIs, submittals and logs, with answers limited to records each user can already see and linked to the source. It is a read-only iOS beta through TestFlight, and no API or MCP tool reaches it, so an outside agent can't use it.

## Before you call either

### 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

### Procore AI Go

1. Don't plan to call Procore AI Go. It's a voice app for people on an iPhone, with no programmatic interface
2. For Procore project data, use Procore's REST API under the customer's OAuth app instead
3. Expect each question asked in the app to use the company's Procore Credits, unless it's on the flat-fee Starter Pack
4. Ask the Procore Company Administrator to join the programme in Procore Explore if a crew needs the app
