⚠️
Known vulnerabilities in dependencies: 3 high
Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.
✅
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
✅
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.

These are read from process.env at runtime. Make sure you trust where they’ll be sent.
// tools this server exposes13 tools

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

list_bins

List all your webhook bins with their URLs and stats

create_bin

Create a new webhook bin to capture HTTP requests. Returns the bin URL you can use as a webhook endpoint.

get_bin

Get details of a specific bin including recent interactions

delete_bin

Delete a webhook bin (soft delete)

list_interactions

List captured HTTP requests (interactions) for a bin

replay_request

Send an HTTP request to any URL (replay/test webhook delivery). The request is executed server-side.

get_replay_status

Check the status of a replay job

list_servers

List available servers (needed for creating bins). Returns server IDs you can use with create_bin.

list_mock_endpoints

List your mock API endpoints (custom HTTP responses at {slug}.rbmock.dev). Useful for finding endpoint IDs and current rule counts.

create_mock_endpoint

Create a mock API endpoint. Returns a live URL ({slug}.rbmock.dev) that responds to HTTP requests with rules you configure. A starter rule (any-method any-path → 200 JSON) is added automatically. Custom slugs require PRO/TEAM; otherwise an auto-slug is generated.

add_mock_rule

Append a routing rule to a mock endpoint. Rules are matched in priority order; the first match wins. After adding rules, call deploy_mock to publish them.

deploy_mock

Publish the current rule set of a mock endpoint to the live mock server. Bumps the configVersion and invalidates edge caches so new requests see the latest rules.

list_mock_captures

List recent captured requests that hit a mock endpoint. Use this to verify your integration is actually calling the mock URL — shows method, path, status, and time for each capture. Returns up to 50 by default.

// known CVEs in dependencies3 high

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

13/13 tools missing one or more hints — list_bins (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); create_bin (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_bin (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +10 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tool inputs are validated

10/13 tool handlers declare input schemas (77%)

Declare an inputSchema with zod/joi/yup on every tool definition.

Tests exist

No test files found

Add tests that exercise each declared tool.

Production dependencies are patched

0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.1 (high), @modelcontextprotocol/sdk@1.12.1 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
