estimate_dividends — Estimate a dividend history
Advertised by the server during the last successful anonymous check.
Advertised read-only

Estimate the reclaimable withholding tax for a whole dividend history in one call: send either a broker export as csv_text with its broker id, or a list of payments (ISIN, payment_date YYYY-MM-DD, gross_amount, currency, optional withheld_amount), max 500. Returns each payment with its source country, treaty rate, reclaimable amount in the residence currency, form and deadline, plus totals per source country. A payment whose source country cannot be resolved is returned as unresolved with no amount; withheld_is_estimated marks a withholding figure estimated from the statutory rate.

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 tax-reclaim-mcp https://api.taxreclaim.eu/api/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 tax-reclaim-mcp --url https://api.taxreclaim.eu/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable tax-reclaim-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "tax-reclaim-mcp": {
