Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions · remote - your agent's requests go to uk-due-diligence-mcp.fly.dev

endpoint auth accepted our unauthenticated MCP initialize - no credentials needed to connect

license MIT - declared in the repository

pypi package uk-due-diligence-mcp - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.paulieb89 is GitHub-verified and matches the repo owner

Capability map

Tools grouped from the project's README - what UK Due Diligence lets an agent do.

Company

5 tools - e.g. Search by name/keyword, filter by status/type; Status, filing compliance, registered address, has_charges summary; Directors/secretaries; each carries an officer_id

company_search · company_profile · company_officers · company_psc · company_charges

Disqualified

2 tools - e.g. Search disqualified directors by name; Full disqualification record: period, Act, associated companies

disqualified_search · disqualified_profile

Charity

2 tools - e.g. Search by name, filter by registration status; Full record: trustees, income/expenditure, governing document

charity_search · charity_profile

Gazette

2 tools - e.g. Corporate insolvency notices across the Gazette's notice-code taxonomy (codes 2401-2465); Full legal wording of a specific notice

gazette_insolvency · gazette_notice

read & search

2 tools - e.g. Fan-out search across all registers - returns IDs (for ChatGPT deep research); Fetch a structured record by ID returned from search

search · fetch

Officer

1 tool - e.g. Full appointment history for a person by officer_id - including dissolved or insolvent companies not named anywhere else

officer_appointments

Land

1 tool - e.g. Price Paid Index sale transactions by postcode - not title ownership (see Limitations)

land_title_search

Vat

1 tool - e.g. Trading name + address as registered for VAT

vat_validate

Limitations (from the README)

Things worth knowing before trusting output: - land_title_search returns Price Paid transactions, not ownership. It does not return current proprietor/title data - HMLR's Price Paid Index only records historic sale transactions. - Sanctions screening is exact/alias matching, not compliance clearance. A company/entity legal name matches reliably; person names with transliteration variants may not. An empty result is n
