MCP integration

Add this tool to your Model Context Protocol server so AI agents can list and call it.

Server configuration

Add this block to your MCP client configuration:

mcp.json

{
  "mcpServers": {
    "elysiatools-csv-filter": {
      "name": "csv-filter",
      "description": "Filter CSV data by column values with multiple conditions and operators.

List available tools

After connecting to the SSE endpoint, list the exposed tools:

tools/list

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

Call this tool

Invoke the tool by its id, passing arguments built from its parameters:

tools/call

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "csv-filter",
    "arguments": {
  "csvFile": "https://example.com/file.ext",
  "filterColumn": "Column name to filter on",
  "filterOperator": "equals",
  "filterValue": "Value to filter by (leave empty for is_empty/is_not_empty)",
  "additionalFilters": "Examples:\n[{\"column\": \"age\", \"operator\": \"greater_than\", \"value\": \"25\"}]\n[{\"column\": \"status\", \"operator\": \"equals\", \"value\": \"active\"}, {\"column\": \"score\", \"operator\": \"greater_equal\", \"value\": \"80\"}]\n[{\"column\": \"name\", \"operator\": \"contains\", \"value\": \"john\"}, {\"column\": \"email\", \"operator\": \"is_not_empty\"}]",
  "outputFormat": "csv",
  "includeHeader": true,
  "caseSensitive": false,
  "trimValues": true
}
  }
}

Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).

File parameters accept a public file URL only (https://…). Local paths, data: URIs, and Base64 strings are not supported.
