CloudBase MCP

Context cost warning: its tools/list is about 56,457 tokens (42 tools), 172% of a 32k context window and 28% 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

90/100

Capped at 90: 2 of 3 real tool calls passed in our test; the tests add up to 100. Why scores are capped

Last tested 2026-11-11 (Fresh: tested within 30 days) Working (tool call tested 2026-11-11) Connects without a key; tool calls need one

No advisories in range for tested 2.37.5 (checked 2026-11-11)

Security review: not tested

Test points add up to 100; the score is capped at 90 because not every real tool call passed. Not a quality or security rating. Why scores are capped

Tested npm @cloudbase/cloudbase-mcp 2.37.5 (MIT; repo TencentCloudBase/CloudBase-AI-Toolkit, 1,163 GitHub stars when checked). Stdio, 42 tools for Tencent CloudBase; replies are mostly in Chinese. Real calls without an account: searchKnowledgeBase full-text docs search and skill lookup both returned content. queryEnv (list environments) returned AUTH_REQUIRED (isError false), counted as not passed: environment, database, function and hosting tools need a Tencent Cloud sign-in. Manage/write tools were not called. Our first docs call left out the required action argument and was rerun with it.
Tool-call test (2026-11-11, direct MCP stdio client, no LLM): partial. 2 of 3 calls passed: docs and skill search work without an account; environment tools need a Tencent Cloud sign-in. Evidence: local test run, Nov 11, 2026.

Transport (tested 2026-11-11): stdio

Token cost (estimate): approx. 56457 tokens, cl100k estimate (42 tools, measured 2026-11-11, version 2.37.5). This is an estimate from our testing of the tool names, descriptions and input schemas, counted with cl100k_base.

What we tested and what we didn't

Tested on 2026-11-11

  • Install from the registry
  • We connected with no credentials and asked for its tool list: it listed 42 tools (Method details: MCP initialize then tools/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.

Known security issues

Checked on 2026-11-11 for version 2.37.5 against OSV, GitHub advisories, GitHub repository advisories. Scope: the package itself; dependencies not scanned.
