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 csv-repair-mcp https://api.rohnelt.dev/csv-repair/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 csv-repair-mcp --url https://api.rohnelt.dev/csv-repair/mcp

Cursor

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

Cursor configuration

{
  "mcpServers": {
    "csv-repair-mcp": {
      "url": "https://api.rohnelt.dev/csv-repair/mcp"
    }
  }
}

Cline

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