Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00038 | $0.00326 |
| Opus 5 | $0.00019 | $0.00163 |
| Sonnet 5 | $0.00008 | $0.00065 |
| Haiku 4.5 | $0.00004 | $0.00033 |
Grade A, and why
app scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
App Plugin
This is the consolidated skill for interacting with your app's API. It covers all MCP tools and REST endpoints.
Available Tools
| Tool | Access | Description |
|---|---|---|
| echo | free | Echo a message back (connectivity test) |
Usage Pattern
- Check if the MCP server is connected (
.mcp.jsonconfig) - If connected, use MCP tools directly
- If not connected, fall back to REST API calls
- For auth-gated endpoints, include the API key
- For x402-gated endpoints, follow the payment flow
Payment Flow (x402)
For paid tools:
- Call the tool WITHOUT a
paymentparameter - Server returns payment requirements (price, network, pay-to address)
- Present the price to the user and ask for confirmation
- If confirmed and agent has wallet: sign and submit payment
- If no wallet: suggest using an API key or the REST endpoint directly
Error Handling
If a tool call fails:
- Check the error code and message
- Present the
suggestionfield to the user - If MCP is unavailable, fall back to REST
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

app is a skill published in the GitHub repository MangroveTechnologies/mangrove-agent (5 stars, last pushed 1mo ago), licensed MIT. It adds 38 tokens to every session and 326 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

phone
Use when the user wants phone-number intelligence (lookup, carrier, line type, SIM-swap / call-forwarding fraud signals), US/CA number provisioning (rent a phone number), or outbound AI voice calls (Bland.ai under the hood — schedule, confirm, follow-up). Pay per call in USDC.
