## Which one, for what

### ClickUp (C)

Good for: Teams already working in ClickUp that want an assistant to create and update tasks, comment, log time and read Docs through one OAuth connection.

Ahead on:
- Reliability, 74 against 69
- Schema & documentation, 74 against 32
- Security & auth, 64 against 51
- Transparency & trust, 75 against 47

Also in its favour:
- A hosted endpoint, with nothing to install
- No incidents deducted, where Redmine loses 4 points for them

Watch for: MCP calls are capped per rolling 24 hours without the Everything AI add-on, 100 on Free Forever and 300 on Unlimited, per Workspace and client

### Redmine (D)

Good for: Teams that already run Redmine or want a free, self-hosted tracker with issues, time entries and wikis under their own control.

Ahead on:
- Payments & pricing, 60 against 30
- Maintenance & community, 73 against 54

Also in its favour:
- Open source

Watch for: No OpenAPI document or other machine-readable contract was found in the wiki or the source repository

## Verdicts

**ClickUp.** The hosted MCP server uses OAuth 2.1 with PKCE, dynamic client registration and read and write scopes, and works on the Free Forever plan. Without the Everything AI add-on, MCP calls are capped at 100 to 25,000 per rolling 24 hours by plan. No API changelog, deprecation policy, official SDK or SLA was found.

**Redmine.** Redmine's REST API covers issues, projects, time entries and 20 other resources, and versions 6.1 and later add OAuth 2 with one scope per permission. The software is free under the GPL. No OpenAPI document exists, most errors return a bare status code, and 24 security advisories were published in twelve months, two rated critical.

## Before you call either

### ClickUp

1. Connect to https://mcp.clickup.com/mcp with OAuth 2.1 and PKCE. API keys and REST OAuth tokens are refused on the MCP server
2. Pass `workspace_id` on every MCP call when the user belongs to more than one Workspace, as ClickUp's own skills instruct
3. Budget MCP calls. Each tool call counts against the rolling 24-hour cap, and `RATE_LIMIT_EXCEEDED` returns `retryAfter`
4. On the REST API read `X-RateLimit-Remaining` and `X-RateLimit-Reset`, and page Get Tasks with `page` at 100 tasks a page
5. Treat `team_id` in API v2 as the Workspace ID, and send dates as Unix milliseconds

### Redmine

1. Ask an administrator to tick Enable REST API under Administration, Settings, API. It is off by default and every call fails until then
2. Send the key in the `X-Redmine-API-Key` header, never as the `key` query parameter, and set `Content-Type: application/json` on every POST and PUT
3. Add `status_id=*` to issue lists. The default returns open issues only, 25 a page with a maximum of 100
4. Comment on an issue by sending `notes` in a PUT to `/issues/<id>.json`. There is no separate comment endpoint
5. A DELETE on a project through the API skips the confirmation the web page asks for, so run the agent as a non-administrator user
