Pipeworx postcodes

Lookup UK postcode details including coordinates, administrative areas, parliamentary constituencies, NHS regions, and validate postcodes.

Security Scan

The skill's instructions, requirements, and behavior are coherent with its stated purpose (UK postcode lookup) — it simply proxies postcode lookup calls to an external Pipeworx endpoint — but you should be aware it sends user-provided postcode data to a third-party URL and the skill's origin is unknown.

Purpose & Capability

Name/description (UK postcode lookup) match the SKILL.md: the skill invokes an external postcode lookup API (gateway.pipeworx.io). No unrelated env vars, binaries, or installs are requested.

Instruction Scope

Runtime instructions are narrowly scoped to making POST requests to the Pipeworx MCP endpoint for lookup/nearest/validate/random operations. The only noteworthy point is that user-provided postcode strings are sent to an external service (https://gateway.pipeworx.io); the SKILL.md does not ask the agent to read local files or other environment data.

Install Mechanism

No install spec or code files are present (instruction-only). Nothing is written to disk or installed by the skill itself.

Credentials

The skill requires no credentials, environment variables, or config paths. The lack of requested secrets aligns with its purpose.

Persistence & Privilege

always is false and the skill does not request persistent system privileges or modify other skills' configuration. Autonomous invocation is allowed (platform default).

Assessment

This skill appears to do what it says: it sends postcode queries to https://gateway.pipeworx.io and returns geographic/admin details. Before installing, consider: (1) the skill will transmit any postcode strings you provide to an external third party — avoid sending sensitive personal data you don't want shared; (2) the skill has no listed homepage or source, so verify you trust Pipeworx/gateway.pipeworx.io and confirm any privacy/usage policies; (3) because this is an external network call, consider rate limits, costs, or data-retention policies of the service; (4) if you are uncomfortable with outbound network calls to an unknown provider, do not enable autonomous invocation or don't install the skill.

Postcodes

UK postcode geographic lookup. Get coordinates, administrative districts, parliamentary constituencies, and NHS regions for any postcode in the United Kingdom.

What you get

• lookup_postcode -- Full geographic and administrative details for a UK postcode
• nearest_postcodes -- Find neighbouring postcodes to a given one
• validate_postcode -- Check if a postcode string is valid
• random_postcode -- Grab a random valid postcode with full details

Try it

Look up 10 Downing Street's postcode:

curl -X POST https://gateway.pipeworx.io/postcodes/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"lookup_postcode","arguments":{"postcode":"SW1A 2AA"}}}'

Good to know

Postcodes are case-insensitive and spaces are optional -- SW1A1AA works the same as sw1a 1aa. The response includes ONS codes, lat/lon coordinates, and full administrative geography down to ward and parish level.
