MCP server and REST API for data, text, code, PDF and web tasks. Requests are processed in memory and not stored.
- MCP endpoint (Streamable HTTP): https://toolsthatdontupload.com/mcp (v1.5.0)
- MCP tools: search_tools, run_tool, list_categories (they search and run the REST catalog)
- REST API: https://toolsthatdontupload.com/openapi.json (every endpoint, generated; every documented example is tested)
- Network tools (fetch URL, DNS, WHOIS, SSL) need an X-API-Key header. Free key: https://toolsthatdontupload.com/api-keys/
Korean tools
Romanization, amounts in Korean words (일금 ...원정), particles (조사), initial consonants (초성), business-number checksum, personal-data masking. Document generation: 견적서 / 거래명세서 (XLSX), 차용증 / 표준근로계약서 (DOCX).
Egress receipts
Every REST response has an X-Egress header and every MCP result has _meta["com.toolsthatdontupload/egress"] listing external hosts contacted (none for most tools).
Files through MCP
PDF tools accept file_base64 / files_base64 (max 10 MB) and return file_base64.
