search_transcriptions — Search Transcriptions
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Full-text search across page transcriptions Performs a full-text search across the page transcriptions of historical documents indexed by Open Archives. Mirrors the search UI at `/transcripties/zoek.php`. Results are ordered by Elasticsearch relevance (the order is fixed and cannot be overridden) and are returned paginated. Each match includes a source citation, page identifier and up to five highlighted text fragments. The set of facets returned depends on the supplied filters.

browse_transcriptions — Browse Transcriptions
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Browse transcriptions hierarchically Returns a hierarchical browse of available page transcriptions. Mirrors `/transcripties/lijst/`. Three modes, depending on the supplied filters: * No filter — top-level list of source archives ordered by total transcription count (descending). * `archive_code` — list of all archive numbers (archieftoegangen) within that archive, ordered by archive number. * `archive_code` + `archive_number` — list of all inventories within that archive number, ordered by inventory number. The order of items is fixed and cannot be overridden. Results are always returned in full (no paging).

view_transcription — View Transcription (IIIF deep-zoom)
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Open one or more transcribed document pages in an interactive deep-zoom viewer with the transcription text alongside. Pass page identifiers returned by search_transcriptions / browse_transcriptions (form <ISIL>_<archive>_<page>, e.g. NL-SdmGA_1504889_11). Optionally highlight a term in the transcript. Hosts without MCP Apps support receive a text summary plus inline preview images.

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 open-archives-mcp https://mcp.openarchieven.nl/

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 open-archives-mcp --url https://mcp.openarchieven.nl/

Cursor

Merge this server into .cursor/mcp.json in your project, then enable open-archives-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "open-archives-mcp": {
      "url": "https://mcp.openarchieven.nl/"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "open-archives-mcp": {
      "type": "streamableHttp",
      "url": "https://mcp.openarchieven.nl/",
      "disabled": false
    }
  }
}

VS Code

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

      "type": "http",
      "url": "https://mcp.openarchieven.nl/"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
