Perplexity

Analyze BINs from the CLI

`bin_lookup` returns the issuer, card type, and country from a 6-digit prefix. You run Claude Code in your terminal to parse a CSV of failed transactions. The agent hits the API and appends the issuing bank to your logs. You get instant visibility into payment failures without leaving your shell. `merchant_industry_codes` pulls the higher-level category groupings. You pipe this data into a shell script to map your internal merchant database to standard network classifications. The MCP Server handles the formatting. You just write the script.

Script fraud reporting pipelines

`submit_fraud_report` sends confirmed fraud cases to the network database. You trigger Claude Code from a cron job. It reads your flagged database records and pushes them to the API automatically. It handles the authentication and request signing behind the scenes. The agent formats the transaction amounts and counterfeit codes perfectly. You don't write the boilerplate. You just give Claude Code the local database access and let it hit the network endpoints headlessly. It runs quietly in the background.

Query Mastercard MCP Server

`nearby_locations` finds points of interest and payment infrastructure near specific GPS coordinates. You use Claude Code to run batch audits on merchant density. It iterates through a list of coordinates and outputs a clean JSON report directly to standard out. `get_merchant` pulls the specific contact info and operating hours. The agent grabs this data and pipes it straight into your monitoring tools. You get real network data without leaving your SSH session. It turns a manual web portal lookup into a single command.

Common questions about Mastercard MCP in Claude Code

Run `claude mcp add --transport http mastercard-mcp -- ` in your terminal. Ensure your flags come before the server name.

Yes. You can point the agent at a local text file of prefixes. It will call `bin_lookup` for each one and output a clean JSON array of the issuing banks.

The agent reads the exact HTTP status and error message from the MCP Server. It can automatically retry the request or log the failure to your standard output.

You can run Claude Code headlessly in a GitHub Action. It can use `search_merchants` to verify location data during your integration test phase.

The server processes raw transaction amounts and 6-8 digit IINs. Claude Code executes these requests entirely within your local shell environment, keeping network traffic confined to the machine running the command.
