Invokera Book Search (Open Library) MCP

This MCP server allows agents to search tens of millions of book and author records via the Internet Archive's Open Library API. It supports searching authors by name and books by keyword, returning bibliographic data such as titles, authors, birth dates, and work counts to help agents answer questions or build reading lists.

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 book-search-open-library-mcp https://invokera.com/r/book-search

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 book-search-open-library-mcp --url https://invokera.com/r/book-search

Cursor

Merge this server into .cursor/mcp.json in your project, then enable book-search-open-library-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "book-search-open-library-mcp": {
      "url": "https://invokera.com/r/book-search"
    }
  }
}

Cline

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

Cline configuration

{
  "mcpServers": {
    "book-search-open-library-mcp": {
      "type": "streamableHttp",
      "url": "https://invokera.com/r/book-search",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start book-search-open-library-mcp and inspect its tools.

VS Code configuration

  "servers": {
    "book-search-open-library-mcp": {
      "type": "http",
      "url": "https://invokera.com/r/book-search"
    }
  }
}

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 book-search-open-library-mcp https://invokera.com/r/book-search

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.

Windsurf

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