How to Install MCP Servers in Claude Code

How to add MCP servers to Claude Code from the terminal — the claude mcp add command, project vs user scope, and how to confirm the server connected.

Step-by-step installation guide

  1. Add the server with the CLI

    Run "claude mcp add <name> -- <command> [args...]". Everything after the -- is the command Claude Code runs to launch the server. Use -e KEY=value to pass environment variables.

  2. Choose a scope

    Add --scope project to write the server into a shared .mcp.json your team commits, or --scope user to make it available across all your projects. Local scope (the default) keeps it to the current project for just you.

  3. Verify the connection

    Run "claude mcp list" to see each server and whether it connected. You can also use the /mcp command inside a Claude Code session to inspect available servers and tools.

    Scan/purge hidden text & score web domains: TLS, DNS, headers, speed. Free scans, $0.01 actions. The Tools:
    • text_scan_v1 — free Scans a text string for invisible Unicode characters, homoglyphs, and normalization issues. Returns a risk score, a list of flagged characters, and detected homoglyphs. Never modifies the input text.
    • text_purge_v1 — $0.01 per call Removes invisible Unicode characters and replaces homoglyphs in a text string, then normalizes the result. Returns the cleaned text plus a before-and-after risk comparison.
    • domain_check_score_v1 — free Overall score, per-category scores, and how many findings each category raised. Use it to triage: rank a list of domains, confirm one is healthy, or decide whether the full report is worth pulling. It tells you which categories are weak and how many issues they hold, but not what the issues are.
    • domain_check_score_batch_v1 — free The same triage scores for up to 100 domains in a single call. One score summary per distinct domain: overall score, per-category scores, and how many findings each category raised. Never the findings themselves.
    • domain_check_v1 — $0.01 per call Full report for one domain: weighted score out of 100, per-category breakdown, and every individual finding with a prioritised remediation order.
    • domain_check_batch_v1 — from $0.005 per domain The same full report for up to 100 domains in a single call, with one payment for the whole batch instead of one per domain. Both cheaper per domain and much faster than calling domain_check_v1 in a loop.

Frequently Asked Questions

Use the terminal: claude mcp add <name> -- <command> [args...]. For example, claude mcp add github -- npx -y @modelcontextprotocol/server-github. Add -e KEY=value for secrets and --scope project or user to control where it is stored.

Project scope writes to a .mcp.json in the repository so your whole team shares the server; user scope stores it in your global config so it follows you across projects. Local (default) scope keeps it to the current project for only you.

Run claude mcp list from the terminal, or use the /mcp slash command inside a session. For verbose connection logs, start Claude Code with the --debug flag.
