AgentDiet A2A Indirect Prompt-Injection & Jailbreak Firewall MCP server

• get_agent_wallet_statusFree

  Inspect an agent's account ledger: remaining free trial calls (out of 5), prepaid USD balance, cumulative spend, total API calls, and total LLM tokens saved. WHEN TO USE: Call before a batch of paid tool executions or after completing a Stripe or USDC top-up to confirm your balance. WHEN NOT TO USE: Do not use to process web content, execute marketplace tools, or submit payments; use the other tools on this server for execution. PARAMETER INTERACTIONS: Omit agent_id to inspect the default trial account derived from your client IP, or pass your explicit agent_id or agd_pass_ session key to check a specific funded wallet. Free and read-only: never charges a fee or consumes a free trial call. Example: get_agent_wallet_status(agent_id='example')

• scan_prompt_injectionFree

  Scans untrusted web pages, emails, MCP responses, or A2A payloads for hidden prompt injections and returns sanitized text. WHEN TO USE: Call `scan_prompt_injection` when your task requires deterministic `prompt-guard` analysis for `text`; use `get_agent_wallet_status` to check your remaining free trial quota or prepaid balance. WHEN NOT TO USE: Do not use for unrelated domains or binary media. PARAMETER INTERACTIONS: Pass the target `text` as a non-empty string; omit `agent_id` and `tx_hash` during your 5 free trial calls, or supply `agent_id` (`agd_pass_...`) / `tx_hash` for paid execution. Read-only and idempotent; results are cached for 1 hour (<5ms cache hit). $0.005 per call. Pricing: the first 5 calls per agent_id are free and failed calls are never charged. After 5 calls, the tool returns a payment-required quote (not a fatal error) with a $2 Stripe top-up link and Base/Solana USDC addresses; complete payment, then retry with your agd_pass_ key in agent_id or pass tx_hash. Example: scan_prompt_injection(text='example')
