How to Install MCP Servers in Cursor

How to install MCP servers in Cursor — the global and per-project mcp.json files, adding a server from Settings, and enabling tools in the Agent.

Browse Cursor servers directory

Step-by-step installation guide

Open MCP settings
Go to Cursor Settings → MCP → Add new MCP server, or edit the JSON directly: ~/.cursor/mcp.json for every project, or .cursor/mcp.json in a project root to scope it to that repo.
Add the server under mcpServers
Add a named entry with a "command" and "args" (and "env" for secrets), using the same stdio shape as other MCP clients.
Enable it and use it in the Agent
Cursor picks up the change automatically; make sure the server is toggled on in the MCP settings. Its tools then become available to the Agent (Composer) — the model calls them when relevant.

Feranor Resilience
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

Cursor reads ~/.cursor/mcp.json for a global configuration available in every project, and .cursor/mcp.json in a project root for servers scoped to that repository. Both use the same "mcpServers" JSON shape as Claude Desktop.

Confirm the server is toggled on in Cursor Settings → MCP, that the command runs on its own in a terminal, and that you are using the Agent (Composer), since MCP tools are called from agent mode. A red status in the MCP panel usually shows the underlying error.

Yes — commit a .cursor/mcp.json to your repository. Anyone who opens the project in Cursor gets the same servers, though each person still supplies their own secrets via env values.
