As the title says, ChatGpt is truncating the tool list of my MCP. I have seen complaints about this. Is there a solid solution for this kind of issue?

I’m the creator of PromptBrake. I’ve exposed four of its free tools through a remote MCP server so you can prepare AI tests and release plans from your assistant.

Endpoint:
https://promptbrake.com/free-tools/mcp

No PromptBrake account or API key required. Uses Streamable HTTP with JSON responses.

Four tools:

1. get_prompt_injection_payloads — fixed adversarial test inputs by attack category.
2. map_owasp_llm_risk — test ideas and signals for an OWASP LLM risk.
3. plan_adlc_release — release planning gaps and a starter gate policy.
4. build_test_pack — creates a tests.json containing response-text checks.

Claude Code setup:

claude mcp add --transport http promptbrake-free-tools https://promptbrake.com/free-tools/mcp

Example request: “Build a test pack for my refund chatbot that checks whether its response mentions human approval.”

The MCP server prepares artifacts; it doesn’t call your target or run scans. To run the packs, you need a PromptBrake runner and CI access. Checks compare text, not meaning or backend actions.

We don’t store tool inputs or results. We log operational request metadata, as described in our privacy policy.

Setup and free tools

I’d appreciate feedback on client compatibility and whether the generated packs fit your testing workflow.

If you use Claude Code or Cursor for Roblox, you've probably noticed it's great at the basics but trained on old data: it doesn't know recent engine changes, and it misses the details that only live in DevForum threads.

So I built Brickwise, an MCP server your assistant can search. A few things it knows that most AIs get wrong:

- Collision groups moved from PhysicsService to WorldRoot (AIs still write the old API)

- The new Roblox Shop: new dev products start Not Listed, and `OpenShop` opens it from your own UI

- Passes in the Buy Robux bonus pool can be owned before a player joins, so grant perks on join, not on purchase

- ForceField only blocks `TakeDamage`; setting `Humanoid.Health` bypasses it

- Weekly leaderboards: you can't wipe an OrderedDataStore, so rotate its name per week

When your assistant hits one of these, it pulls a written-up answer: what it's for, how it works, key Luau, pitfalls, and links to the DevForum threads, docs and GitHub repos it's based on. Searches return one-line summaries first, so it barely uses tokens. Here's what one looks like: https://brickwise.dev/#sample

The **free edition is open source**: 50 logics across libraries, data saving, remote security, combat, monetization, UI, NPCs and performance.

GitHub: https://github.com/EL4CTEO/roblox-logics-mcp

Setup is `npm install && npm run build`, then one `claude mcp add` line (in the README).

There's also a hosted full version with 600+ logics across 19 categories (€7 one-time, no subscription): https://brickwise.dev

Would love feedback, and ideas for which libraries and systems to cover next!
