Tpscheck MCP with Claude: Check UK Phone Numbers Before Marketing Calls
The short answer
Claude works with Tpscheck through the Model Context Protocol (MCP), a secure standard that lets Claude use the tool with permissions you control. Once connected, Claude can check UK phone numbers against the TPS and CTPS registers, validate number types, and fetch location data, all from natural language requests, with your team reviewing results before any call is made.
What is Tpscheck?
Tpscheck is a real-time service for checking UK phone numbers against the Telephone Preference Service (TPS) and the Corporate Telephone Preference Service (CTPS). These registers list numbers whose owners do not want unsolicited marketing calls. Marketing teams, call centres, lead generation firms, debt and insurance businesses, and compliance teams use Tpscheck to screen call lists before dialling. It also helps confirm number types and providers, which supports cleaner, more accurate contact data.
How Claude connects to Tpscheck through MCP
The Model Context Protocol (MCP) is an open standard that lets Claude securely use other software. Think of it as a universal adapter between Claude and the tool. Your organisation decides exactly what Claude can access, and access is set up using the sign-in method Tpscheck supports, an API key.
Once connected, Claude can read and act within Tpscheck according to the permissions you grant. Typically this means submitting a batch of phone numbers, checking each against the TPS and CTPS registers, validating number types, and fetching location data, then returning a clear summary your team can use.
Permissions and approvals keep people in charge. We set access to the least privilege needed, so Claude only performs the checks you approve. Results can be routed to a person for review before a campaign list is finalised, and every check is recorded in audit logs so you can show how contact lists were screened.
What you can automate
Screening outbound marketing lists
Before a campaign launches, Claude can take a list of UK numbers, run them through Tpscheck, and separate those registered with TPS or CTPS from those that can be called. Marketing managers receive a clean list and a summary of how many numbers were removed, reducing the risk of contacting people who have opted out.
Cleaning lead data from third parties
When purchasing or receiving lead lists from partners, operations teams can use Claude to check every number against the registers in one pass. This helps confirm that bought-in data has been screened before it reaches sales agents, supporting due diligence on lead sources.
Supporting call centre compliance
Compliance officers can ask Claude natural language questions such as which numbers in yesterday's dialler file were not checked, or which entries need re-verification. Claude gathers the answers from Tpscheck so the compliance team spends less time on manual lookups.
Validating contact data quality
Customer data teams can use Claude to confirm number types and providers, flagging numbers that look mobile, landline or invalid. Cleaner records mean fewer failed calls, better reporting and more reliable customer databases.
Answering internal screening queries
Sales leaders and account managers often need quick answers about whether a particular number can be contacted. Through a secure chatbot connected via Claude, staff can ask in plain English and receive a checked answer with the relevant register status.
An end-to-end workflow: Pre-campaign TPS and CTPS screening with CRM update
TriggerA marketing manager uploads a new prospect list to the shared drive ahead of a campaign.
Claude reads the prospect list from the shared folder and extracts the phone numbers.
Claude submits the numbers to Tpscheck and checks each against the TPS and CTPS registers.
Claude validates number types and flags numbers that appear invalid or unusual.
Claude produces a summary showing numbers cleared to call, numbers registered, and numbers needing review.
The marketing manager approves the summary, and Claude updates the contact statuses in the CRM so that only cleared numbers enter the dialler queue.
The audit log records the checks, the approver and the time of the update.
OutcomeCampaigns start with a screened list, the CRM reflects each contact's status, and the team has a documented record of its checks, supporting compliance with UK telemarketing rules. Typical results vary by list quality and process.

Frequently asked questions
What does the Tpscheck MCP server do?
The Tpscheck MCP server acts as a secure bridge between Claude and the Tpscheck service. It lets Claude send phone numbers for checking against the TPS and CTPS registers, validate number types and providers, and fetch location data, within the permissions you set. The server does not change how Tpscheck itself works; it simply makes the service available to Claude in a controlled way.
Is connecting Tpscheck to Claude secure?
Security comes from how the connection is set up. We use the API key sign-in method, store the key securely, and grant least-privilege access so Claude can only perform the checks you approve. Actions are logged, and people approve consequential steps. We design around your own security and data protection policies.
What can Claude do with Tpscheck once connected?
Typically, Claude can check batches of UK phone numbers against TPS and CTPS, confirm number types and providers, retrieve location data, and summarise the results in plain English. It can also answer natural language questions from staff, such as whether a specific number can be contacted, always within the access you have granted.
How long does setup take?
Timelines depend on the complexity of your workflow and how many systems it connects to. A focused screening workflow can often be set up and tested within a few weeks, while broader workflows involving your CRM, dialler and reporting take longer. We confirm the timeline after the free automation audit.
What access or plan is needed to use Tpscheck with Claude?
Generally, you need an active Tpscheck account with API key access so the connection can be set up. The exact access your team requires depends on the checks you plan to run. During the free audit we confirm what your current setup supports and what, if anything, needs to be arranged with Tpscheck first.
