mcp-feedback

mcp-feedback is a skill for Claude Code, Codex from unbounce/agent-plugins. It costs 146 tokens per session (1,117 once invoked), scanned A, original, MIT.

A reporting workflow for sending feedback about Unbounce MCP tools to their team. MCP tools are services that let an agent use external systems.

In plain words
What is it for?
For submitting faithful feedback about what happened while using Unbounce MCP tools, including bug context when available.
Why use it?
It records bugs, praise, feature requests, confusion, or other feedback without requiring the user to copy it into another system. It reports the issue rather than repairing it.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcp-feedback scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Submit Unbounce MCP feedback

Record the user's feedback about the Unbounce MCP tools to the team's store by calling the submit_feedback tool. The tool persists the record server-side, so nothing has to be copied out of the conversation into Slack or anywhere else.

The mcp- prefix here means "pertains to Unbounce MCP," not "about a page." This skill is about capturing feedback on the MCP tools themselves — whether they broke, delighted, confused, or fell short.

Hard rule: report, don't repair

Do NOT try to fix, retry, or work around the thing being reported. This skill records feedback on what already happened. Never invent tool-call arguments or error text — anything not actually present is unknown. (Fixing the underlying task, if the user wants that, is separate work done after the feedback is recorded.)

1. Gather the feedback

Settle two things — from the conversation where possible, asking only what you can't infer:

  • type — one of bug · praise · feature_request · confusion · other.
  • message — the feedback in the user's own words. Keep it faithful; don't editorialize.

For a bug, also assemble the context: the verbatim failing tool call(s) from the transcript — exact tool name, exact arguments JSON, and the raw result/error text (call out any code/reason/remedy fields). Include the relevant one(s), especially the failing call. If the failure happened in another session and isn't in the transcript, ask a couple of targeted questions and mark transcript-only fields (exact arguments, exact raw error) as unknown. For non-bug types, context is usually unnecessary — include a light pointer (the tool or page in question) only if it genuinely helps.

Login / connection problems are a bug: capture what the user was doing, the client they're in, and the exact error text (e.g. access denied, invalid_grant, a failed redirect, repeated re-login prompts). Note that if the MCP can't connect at all, submit_feedback itself won't be reachable — that's expected, and step 4's inline fallback is how the feedback still gets out.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
