Our review
Queries the Mantle Core API in read-only mode via the mcli CLI tool, providing access to customers, subscriptions, metrics, transactions, and other platform data.
Strengths
- Full read-only access to Mantle data without needing the web interface.
- Supports pagination and filters to retrieve large datasets.
- JSON output easily parsable with tools like jq.
Limitations
- Restricted to read-only operations (no create/update/delete).
- Requires pre-authenticated CLI (no direct API token management).
- List commands limited to 100 items per request with pagination.
When you need to quickly look up Mantle data (customers, metrics, subscriptions) via a scriptable command-line interface.
When you need to create, update, or delete Mantle resources, as mcli is strictly read-only.
Security analysis
SafeThe skill explicitly restricts usage to read-only commands and warns against mutations. It does not instruct any destructive, exfiltrating, or obfuscated actions. The CLI tool is pre-authenticated and used only for querying data.

Examples
Look up customer 'Acme Corp' in Mantle and show their subscriptions and recent timeline.Check the MRR for the last 30 days in Mantle and output the results as JSON.Search Mantle entities for 'john@example.com' and list all associated customers and contacts.name: mcli description: > Query the Mantle Core API using the mcli CLI tool. Use this skill when the user asks to look up, query, list, get, or investigate data from the Mantle platform — customers, subscriptions, metrics (MRR, ARR, churn, etc.), apps, plans, deals, contacts, usage events, charges, transactions, affiliates, tickets, meetings, email campaigns, email deliveries, or any other Mantle resource. Triggers on: "look up customer", "check MRR", "find subscription", "get metrics", "query usage events", "list deals", "search entities", "list email campaigns", "check email deliveries", or any request to read data from the Core API. This skill is READ-ONLY — never use mcli to create, update, or delete data.
mcli — Mantle Core API CLI
Query Mantle data via the mcli command. This skill covers read-only operations only.
Key Rules
- Read-only: Only use
list,get,search,timeline, andmetricssubcommands. Never usecreate,update,delete,add-*,remove-*, or any mutating command. - Always use
--jsonwhen you need to parse or analyze the output programmatically. - Pagination: Most list commands default to 25 items. Use
--taketo get more (up to 100) and--cursoror--pagefor pagination. - The CLI is pre-authenticated. Run
mcli whoamiif you need to confirm the current profile.
Quick Patterns
Look up a customer
mcli customers list --search "acme" --json
mcli customers get <id> --json
mcli customers get <id> --includes subscriptions --json
mcli customers timeline <id> --json
Check metrics
mcli metrics mrr --date-range last_30_days --json
mcli metrics arr --app-id <id> --json
mcli metrics revenue-churn --date-range this_month --json
mcli metrics sales --json
Find subscriptions
mcli subscriptions list --customer-id <id> --json
mcli subscriptions get <id> --json
Search across contacts and customers
mcli entities search --search "john@example.com" --json
View app events / usage
mcli apps list-events --app-id <id> --take 50 --json
mcli usage-events list --customer-id <id> --event-name "page_view" --json
mcli metrics usage-event --app-id <id> --event-name "api_call" --date-range last_7_days --json
Deals and pipeline
mcli deals list --status open --json
mcli deals get <id> --json
mcli deals timeline <id> --json
Charges and transactions
mcli charges list --customer-id <id> --json
mcli transactions list --customer-id <id> --app-id <id> --json

Tips
- Use
mcli <resource> help <subcommand>to see all options for any command. - Pipe
--jsonoutput tojqfor filtering:mcli customers list --json | jq '.customers[] | .name' - Date ranges accept presets (
last_30_days,this_year, etc.) or custom ISO 8601 dates via--start-date/--end-date. - When investigating a customer, start with
entities searchto find them, then drill intocustomers get,subscriptions list,charges list, etc.
Email campaigns and deliveries
mcli email-campaigns list --status active --json
mcli email-campaigns get <id> --json
mcli email-campaigns preview <id> --customer-id <cust_id> --json
mcli email-deliveries list --email-id <campaign_id> --json
mcli email-deliveries get <id> --json
mcli email-layouts list --json
mcli email-senders list --json
