AI does not see the tool upload_assets to upload files to a BlazeMeter test

[benjithompson]

Issue: When asking AI to use the BlazeMeter MCP to upload test files to a test, it generally responds with something similar to the following:

The MCP only supports read/create/delete/list/search — no script upload or config update. Checking whether I can finish the job via the REST API

Desired State: The BlazeMeter MCP should surface the upload_assets tool more explicitly so AI knows it's a valid tool more easily.

Hi @benjithompson

Please specify the model, version, and AI agent being used, as well as the specific request made to the AI ​​and your reasoning for identifying where the AI's decision error occurred.

We haven't identified these problems in our tests. Except in older models with low capacity and poor function handling capabilities, which are neither suitable nor recommended for agent mode.

Generally, most major clients have already removed the older models (they used them because they were cheap), but some users may be testing with open-source models that have limited function understanding and calling capabilities, reporting MCP problems when the actual issues lie with the model's capacity.

In general, it is recommended that you use a mature MCP client with mature AI models for handling function calls.

Clients we tested with: Cursor, Claude Code CLI, Claude Desktop, VSCode Copilot (with recent models).
Models we recommend: Claude Sonnet 4.6+, Claude Opus 4.6+, Claude Haiku 4.5+, GPT 5+, Gemini 3.1+

• The plus sign indicates that from that version onward, preferably in medium to high-level thinking configurations (if available).

We would appreciate it if you could provide us with more information so we can reproduce it. By reproducing it, we can see which reasoning model it uses and what hints or hint format it needs to associate or correlate with the correct tool based on the language used.
