Changes things 6Creates or changes something that can be changed back.Claude Code: ask

dataset_columnsThe columns, which of them are numeric, the row count and the provenance banner of the Send A Parcel Compare dataset.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
The columns, which of them are numeric, the row count and the provenance banner of the Send A Parcel Compare dataset. Call this first to learn the schema.
dataset_provenanceThe source, the date it was computed, the licence and the citation for the Send A Parcel Compare dataset.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
The source, the date it was computed, the licence and the citation for the Send A Parcel Compare dataset. Read this to attribute a figure correctly.
dataset_rowThe rows of the Send A Parcel Compare dataset where a column equals a value exactly (case-insensitive).No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
The rows of the Send A Parcel Compare dataset where a column equals a value exactly (case-insensitive).
dataset_topThe highest (or lowest) rows of the Send A Parcel Compare dataset by a numeric column — "which is the most/least X".No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
The highest (or lowest) rows of the Send A Parcel Compare dataset by a numeric column — "which is the most/least X".
enquiry_fieldsEvery field of the Send A Parcel Compare enquiry: key, label, type, whether required, help text and the allowed options where there are any.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Every field of the Send A Parcel Compare enquiry: key, label, type, whether required, help text and the allowed options where there are any. Pass answers to submit_enquiry keyed by field key.
submit_enquirySubmits an enquiry to Send A Parcel Compare — NOT a purchase, NOT a guaranteed quote.No findings
Why it is in this group
- The name "submit_enquiry" says "submit": a word for a change.
Description, as the server wrote it
Submits an enquiry to Send A Parcel Compare — NOT a purchase, NOT a guaranteed quote. Step 1: call with the answers (keyed by field key from enquiry_fields) and consent=true; it validates and returns a summary, the consent line and a confirmation token — show the person the summary and the consent line. Step 2: only if the person agrees, call again with the same answers, consent=true and the confirmation token; the enquiry is then submitted, and the person receives an email with a link they must click before any provider sees it. Consent means the person has read and agreed to: "By submitting you agree Send A Parcel Compare shares your details with parcel carriers and booking brokers who may contact you with a price."

Only reads 4Looks things up and changes nothing.Claude Code: allow

dataset_compareThe rows of the Send A Parcel Compare dataset whose column is any of the given values, in the order given — for "X vs Y" questions.No findings
Why it is in this group
- The name "dataset_compare" says "compare": a word for reading.
Description, as the server wrote it
The rows of the Send A Parcel Compare dataset whose column is any of the given values, in the order given — for "X vs Y" questions.
dataset_searchRows of the Send A Parcel Compare dataset whose cells contain the query (case-insensitive), up to 50.No findings
Why it is in this group
- The name "dataset_search" says "search": a word for reading.
Description, as the server wrote it
Rows of the Send A Parcel Compare dataset whose cells contain the query (case-insensitive), up to 50.
dataset_statscount, min, max, mean, median and sum of a numeric column of the Send A Parcel Compare dataset (grouping commas and currency are handled; non-numeric rows are excluded and counted)…No findings
Why it is in this group
- The description's first verb is "count": a word for reading.
Description, as the server wrote it
count, min, max, mean, median and sum of a numeric column of the Send A Parcel Compare dataset (grouping commas and currency are handled; non-numeric rows are excluded and counted).
enquiry_describeRead first.No findings
Why it is in this group
- The name "enquiry_describe" says "describe": a word for reading.
Description, as the server wrote it
Read first. States plainly what submit_enquiry does on Send A Parcel Compare: it starts an enquiry with human providers who quote directly. Nothing is bought, ordered or paid; no quote is guaranteed; it is free. Also returns who receives the details, the consent wording, and how the person confirms.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

Reads private data0: Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write0: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Remote posture

What anyone on the internet sees at the remote endpoint: an anonymous initialize and tools/list, and the public OAuth metadata.

Looked at Oct 22, 2026, 14:40 UTC, unchanged since Oct 22, 2026. No credentials were sent and no tool was called. What is looked at.

Reachable: yes
HTTP status of an anonymous initialize: 200
tools/list served without credentials: yes
Tools that change things, listed without credentials: 6
Protocol version: 2025-06-18
WWW-Authenticate on 401: not observed
resource_metadata in WWW-Authenticate: none
RFC 9728 protected resource metadata: none
Authorization servers: none
Legacy HTTP+SSE transport: no
Dynamic client registration: not observed

WarnThe whole server
The endpoint served tools/list without credentials, and the list has 6 tools that change things (6 write). Whether a call also works without credentials was not tested: tools are never called.
Matched text
https://sendaparcelcompare.com/mcp: tools/list returned 10 tools to an anonymous client, including dataset_columns (write), dataset_row (write), dataset_top (write), dataset_provenance (write), enquiry_fields (write) and 1 more

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as site. Review it before you use it.

Keep track

Get told when this server's tools change: a new tool, a new description, a new class.

Anlyon alternative

6 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
