Keboola MCP (official)
Context cost warning: its tools/list is about 36,363 tokens (47 tools), 111% of a 32k context window and 18% of a 200k window, before you send a single message. Load only the tools you need, or expect most of the context to go to tool definitions. Estimate from our testing of the tool names, descriptions and input schemas, counted with cl100k_base, measured 2026-11-11. How MCP context cost adds up
Capped at 70: no passing tool call yet; the tests add up to 100. Why scores are capped
Test points add up to 100; the score is capped at 70 until a tool call passes. Not a quality or security rating. Methodology

Tested PyPI keboola-mcp-server 1.112.2 (server reports Keboola MCP Server 4.1.2; repo keboola/mcp-server). Its 47 tools listed without credentials, but calls need a Keboola project: get_flow_schema and docs_query both returned 'This session has no Keboola credentials. Call the "create_project" tool... or run "keboola-mcp-server login"' (live endpoint probe, Nov 3, 2026). We did not call create_project (it would create an account/project). Keboola's hosted endpoint https://mcp.us-east4.gcp.keboola.com/mcp answered HTTP 401 with an OAuth challenge and is not listed separately. Score capped: no passing tool call.

What we tested and what we didn't
Tested on 2026-11-03
- Install from the registry
- We connected with no credentials and asked for its tool list: it listed 47 tools (Method details: MCP
initializethentools/list) - Maintenance signals (last push, archived/deprecated status)
- Docs (README length, install and config example)
- License (OSI-approved or not)
- Token cost (estimate)
Not tested
- Security: not audited (no code review, no permission or data-flow analysis)
- Real tasks (no functional task runs yet)
- Behaviour with real credentials or a real account
- Performance, rate limits or load
- Correctness of results beyond the listed tasks
Methodology: how we test. A high score means it installs and responds, not that giving it access to your data carries no risk.
