Quick start

Call this tool from your code in three languages.

cURL

# 1) Request a presigned URL → returns { uploadUrl, storageKey }
curl -X POST 'http://127.0.0.1:3003/api/upload/presign/mvt-mapbox-vector-tile-pmtiles-google-mvt-projection-and-tilelive-encoding-auditor' \
  -H 'Content-Type: application/json' \
  -d '{"filename":"tileFile.ext","contentType":"application/octet-stream","size":12345}'

# 2) PUT the file bytes directly to the presigned uploadUrl
curl -X PUT '<presigned uploadUrl>' \
  --data-binary @/path/to/file.ext

# 3) Call the tool, passing the returned storageKey for each file field
curl -X POST 'http://127.0.0.1:3003/en/api/tools/mvt-mapbox-vector-tile-pmtiles-google-mvt-projection-and-tilelive-encoding-auditor' \
  -F 'tileFile=uploads/2026/01/01/your-tool-1700000000000-abc123.ext' \
  -F 'tileZ=10' \
  -F 'tileX=512' \
  -F 'tileY=384'

API reference

Send a POST request with your inputs as JSON. File parameters require a separate upload first.

Endpoint

HTTP

POST http://127.0.0.1:3003/en/api/tools/mvt-mapbox-vector-tile-pmtiles-google-mvt-projection-and-tilelive-encoding-auditor

Parameters

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-mvt-mapbox-vector-tile-pmtiles-google-mvt-projection-and-tilelive-encoding-auditor": {
      "name": "mvt-mapbox-vector-tile-pmtiles-google-mvt-projection-and-tilelive-encoding-auditor",
      "description": "Audit .mvt/.pbf vector tiles and PMTiles v3 archives against the Mapbox Vector Tile Specification 2.x: protobuf Layer/Feature/Value decoding, MoveTo/LineTo/ClosePath command-stream validation, ring winding and tag indexes, Web Mercator Google-tile XYZ bounds, PMTiles v3 directory decoding and tile-size vs feature-count budgets.",
      "baseUrl": "http://127.0.0.1:3003/mcp/sse?toolId=mvt-mapbox-vector-tile-pmtiles-google-mvt-projection-and-tilelive-encoding-auditor",
      "command": "",
      "args": [],
      "env": {},
      "isActive": true,
      "type": "sse"
    }
  }
}

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": "mvt-mapbox-vector-tile-pmtiles-google-mvt-projection-and-tilelive-encoding-auditor",
    "arguments": {
  "tileFile": "https://example.com/file.ext",
  "tileZ": 10,
  "tileX": 512,
  "tileY": 384
}
  }
}

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.
