Your MCP tools list in one host and vanish in another.

We run your MCP server live in Claude Code, show exactly which tools that host drops or rejects and why, and — if you want — send a pull request with the fix or workaround.

Fixed scope. US$150 for the check, US$300 with the fix.
No payment before delivery: you have 5 working days after delivery to accept or use one dispute round (a mismatch report or the free rerun), which pauses issuance of the payment request for at most 10 working days. Exactlane issues the payment request after acceptance, due within 7 calendar days, under the Services Terms.

Claude Code debug log

Skipping tool "subscriptions_list": its input schema would be rejected by the Anthropic API (property key "uids[]" does not match /^[a-zA-Z0-9_.-]{1,64}$/).

Sample, not commissioned. Listing stage only; no tool was called. Paid packages currently live-check Claude Code; this figure is evidence only.

Two packages, fixed price

Both cover one MCP server. You get a report either way; the second adds a pull request.

What comes back

A report tied to one runIt names the artifact, the host, and the versions. Every finding is tied to that run.
Evidence the host can useFor suspected host bugs, a minimal repro you can attach to an issue with the host.
Steps you can rerunRecheck steps for the named versions, so you can confirm the result yourself.

A worked sample

Claude Code 2.1.282 dropped subscriptions_list from the public package pushpad-mcp@0.1.1 because two property names contain brackets. Renaming those two keys got the tool listed. Read the sample report.
