WHAT IT DOES

What check_agent_attestation does on Ainumbers Mcp Apps

AI agents call check_agent_attestation to retrieve information from Ainumbers Mcp Apps without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

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.

RISK

Why check_agent_attestation is rated Low

Verifies compliance status and attestation data without modifying records or executing external operations.

From the tool's definition checks agent identity & authorization attestation, deterministic compute, no data modification

RECOMMENDED RULE

The rule that runs check_agent_attestation 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 check_agent_attestation, this is the rule to start with:

check_agent_attestation Allowed

check_agent_attestation is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

{
  "version": "1",
  "default": "deny",
  "tools": {
    "check_agent_attestation": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Ainumbers Mcp Apps, apply this rule, and every check_agent_attestation call is checked against it from then on.

FAQ

Questions about check_agent_attestation

What does the check_agent_attestation tool do? +

Agent Identity & Authorization Attestation Checker: OpenChainGraph compute node (compliance_mandate). Regulatory deadline: 2027-12 (EU AI Act Annex III high-risk obligations (Digital Omnibus, Parliament final approval June 2026) push agent KYA toward compliance requirement from 2 December 2027; KYA-OS donated to DIF March 2026). 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-01-ap2-mandate-chain-validator, art-13-eudi-wallet-credential-readiness-checker. Output feeds: art-02-agent-spend-policy-simulator, ptg-01-ap2-prompt-template-generator. Open at: https://ainumbers.co/chaingraph/art-04-agent-identity-attestation-checker.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. It is categorised as a Read tool in the Ainumbers Mcp Apps MCP Server, which means it retrieves data without modifying state.

What parameters does check_agent_attestation accept? +

check_agent_attestation accepts 4 parameters: compute, parent_hashes, parent_tool_ids, policy_parameters. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on check_agent_attestation? +

Register the Ainumbers Mcp Apps MCP server in PolicyLayer and add a rule for check_agent_attestation: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Ainumbers Mcp Apps. Nothing to install.

What risk level is check_agent_attestation? +

check_agent_attestation is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit check_agent_attestation? +

Yes. Add a rate_limit block to the check_agent_attestation rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block check_agent_attestation completely? +

Set action: deny in the PolicyLayer policy for check_agent_attestation. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides check_agent_attestation? +

check_agent_attestation is provided by the Ainumbers Mcp Apps MCP server (postoaklabs/ainumbers-mcp-apps). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
