Server-provided instructions

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

Agent Bazaar is a catalog of finished digital products from Gragg Robotics, LLC (Maine, USA): spreadsheet tools for small businesses and trades (Excel/Google Sheets), Python automation source code, a Claude Code token-cost optimizer, done-for-you AI automation and website services, and 14 free pricing calculators. Use search_catalog to find an item that fits what your user needs. Products have a USD price and store links (Etsy, Payhip or Gumroad) where the person completes the purchase; services are bought by quote (form or email). If nothing fits, request_product tells us what to build. Searches and requests are recorded to improve the catalog; please don't include personal information.

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 agent-bazaar-mcp https://graggrobotics.com/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 agent-bazaar-mcp --url https://graggrobotics.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable agent-bazaar-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "agent-bazaar-mcp": {
      "url": "https://graggrobotics.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "agent-bazaar-mcp": {
      "type": "streamableHttp",
      "url": "https://graggrobotics.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start agent-bazaar-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "agent-bazaar-mcp": {
      "type": "http",
      "url": "https://graggrobotics.com/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http agent-bazaar-mcp https://graggrobotics.com/mcp

Claude Desktop

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

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
