MCP Tool Usage Examples
This tool can be called via the MCP (Model Context Protocol) endpoint. Here are examples of how to use it:
JSON-RPC Call Example:
POST to https://venue-2.covia.ai/mcp
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/call",
"params": {
"name": "covia_aggregate",
"arguments": {
"input": "your input here"
}
}
}
cURL Example:
curl -X POST https://venue-2.covia.ai/mcp \\
-H "Content-Type: application/json" \\
-d '{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/call",
"params": {
"name": "covia_aggregate",
"arguments": {
"input": "your input here"
}
}
}'
Python Example:
import requests
import json
url = "https://venue-2.covia.ai/mcp"
payload = {
"jsonrpc": "2.0",
"id": 1,
"method": "tools/call",
"params": {
"name": "covia_aggregate",
"arguments": {
"input": "your input here"
}
}
}
response = requests.post(url, json=payload)
result = response.json()
print(result)
JavaScript/Node.js Example:
const fetch = require('node-fetch');
const url = 'https://venue-2.covia.ai/mcp';
const payload = {
jsonrpc: '2.0',
id: 1,
method: 'tools/call',
params: {
name: 'covia_aggregate',
arguments: {
input: 'your input here'
}
}
};
fetch(url, {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify(payload)
})
.then(response => response.json())
.then(data => console.log(data));
Asset Metadata
{
"name": "Aggregate Lattice Entries",
"description": "Count the entries a given number of levels below a lattice path, optionally grouped by a field. A 'step' is one navigation into a container (map/Index value, vector/set element), uniform across types. Use this for authoritative tallies over nested data (e.g. 'how many records under w/health/appointments' with depth=2, or 'how many per source' with groupBy=source) instead of listing and counting client-side. count is always returned; groupBy adds a per-group breakdown. Reads only — creates no job.",

"input": {
"type": "object",
"properties": {
"path": {
"description": "Any resolvable lattice path whose sub-tree you want to tally. Examples: 'w/health/appointments', 'g' (your agents), 'j' (your jobs)."
},
"depth": {
"type": "integer",
"description": "How many get-steps below path to count (default 1 = direct children/elements). A branch shorter than depth contributes nothing."
},
"groupBy": {
"type": "string",
"description": "Optional field read off each visited entry to partition the count. May be a relative path like 'meta/source'. Entries missing the field group under the 'null' key."
}
}

"output": {
"type": "object",
"properties": {
"exists": { "type": "boolean", "description": "True if a countable collection is present at the path (false for an absent path or a scalar)." },
"count": { "type": "integer", "description": "Number of entries visited at the given depth." },
"groups": { "type": "object", "description": "Present only with groupBy: maps each distinct field value to a { count } object. Sum of group counts equals count." }
}
