Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

NexusBro audits public websites for SEO, page speed, broken links, accessibility and security headers. audit_website returns a health score, the top issues, a fix prompt for the user to copy into their coding agent and a link to the full report. audit_checks lists the checks the audit runs.

audit_website — Website and SEO audit (free)

Advertised by the server during the last successful anonymous check.

Advertised read-onlyOpen-world

Audits a public website: crawls up to 5 pages and returns a health score from 0 to 100, the top issues (SEO, page speed, broken links, accessibility, security headers), a fix prompt the user can copy into their coding agent, and a link to the full report. Use it when the user asks to audit, check or improve a website or a landing page. Takes 20 to 90 seconds.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http nexusbro-mcp https://nexusbro.com/api/agents/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add nexusbro-mcp --url https://nexusbro.com/api/agents/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable nexusbro-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "nexusbro-mcp": {
      "url": "https://nexusbro.com/api/agents/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
    "nexusbro-mcp": {
      "type": "streamableHttp",

gemini mcp add --transport http nexusbro-mcp https://nexusbro.com/api/agents/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
