Marketplace search MCP: MCP server, setup and security

What Marketplace search MCP does

According to its repository: “Search TCGPlayer, Reverb and Thumbtack, verify US contractor and nurse licenses, and look up PSA card grading population data.”

An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. Marketplace search MCP is listed under Web search and extraction, a category of 159 servers in the directory, where it ranks #135 by stars.

Topics declared by the repository: ai-tools, claude, contractor-license, data-extraction, license-verification, marketplace.

Installing and connecting Marketplace search MCP

Distribution modes declared in the official MCP registry:

• npm package (Node.js, usually started with npx)

Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: TypeScript.

Security: what to check

An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.

Points found for Marketplace search MCP:

• No licence: without a licence the code is not legally reusable, even if it is public. Avoid it in a company setting without the author's agreement.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on March 18, 2026, the lulzasaur9192/marketplace-search-mcp repository has 5 stars and 0 forks, with 0 open issues. It has more stars than 13% of the servers in the directory. Last change 7 months ago. Version published in the registry: 2.0.0 (March 25, 2026).

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
