WHAT IT DOES

What draft_ap2_mandate_credential does on Ainumbers Mcp Apps

AI agents use draft_ap2_mandate_credential to create or update resources in Ainumbers Mcp Apps, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ainumbers Mcp Apps environment.

Parameter	Type	Required	Description
`compute`	string	—	Compute mode (v0.4 Compute Binding). "auto" (default) = server for gpu:false nodes with registered kernels; "server" = force server-side; "browser" = always ret
`parent_hashes`	array	—	execution_hash values from upstream ChainGraph AP2 artifacts to chain from (sets chain.parent_hashes in the export).
`parent_tool_ids`	array	—	tool_id values matching parent_hashes, in the same order.
`policy_parameters`	object	—	Input parameters for this tool's decision function. For gpu:false nodes with a registered kernel, these are computed server-side when compute is "auto" or "serv

Parameters from the server's own tool schema.

RECOMMENDED RULE

The rule that runs draft_ap2_mandate_credential safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Ainumbers Mcp Apps, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For draft_ap2_mandate_credential, this is the rule to start with:

draft_ap2_mandate_credential Rate-limited

draft_ap2_mandate_credential stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about draft_ap2_mandate_credential

What does the draft_ap2_mandate_credential tool do? +

Google AP2 Mandate Builder: OpenChainGraph compute node (payment_policy). Deterministic OpenChainGraph compute node. By default (compute:"auto") inputs are computed server-side on Cloudflare Workers for gpu:false nodes with a registered kernel; compute:"browser" forces client-side execution and returns a browser delegation URL instead. gpu:true nodes always delegate to the browser. Inputs are processed transiently to compute the response and are not stored, logged, or retained. Use synthetic or anonymised inputs only. Exports an AP2 artifact with execution_hash for chain provenance. Consumes upstream artifacts from: art-15-agentic-mandate-sandbox, art-22-agentic-payments-protocol-comparator, art-27-agentic-readiness-diagnostic. Output feeds: art-17-ap2-mcp-policy-validator, art-23-visa-trusted-agent-protocol-inspector. Open at: https://ainumbers.co/chaingraph/art-16-google-ap2-mandate-builder.html FV-status (published/proven/still-trusted for this spec): /fv-status/8b5ae30d812cd234cfb6068c4ce2022f01d10f2a358979b0f0d73421e09d2543.json — a snapshot, not a subscription; this receipt verifies offline regardless of whether that file is ever fetched.
