AI agents call check_irrbb_csrbb_scope to retrieve information from Ainumbers Mcp Apps without modifying anything — 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.
This tool is a compliance scope checker that retrieves and analyzes regulatory compliance data (IRRBB/CSRBB scope) and generates a read-only artifact with provenance tracking. It performs deterministic computation with no side effects, no PII handling, and no external data modification.
From the tool's definition Tool description explicitly states 'Runs deterministically in-browser; zero PII, zero egress' and 'Exports an AP2 artifact with execution_hash for chain provenance.' It consumes upstream artifacts and produces outputs for downstream diagnostics.

IRRBB CSRBB Scope Checker — OpenChainGraph compute node (compliance_mandate). Runs deterministically in-browser; zero PII, zero egress. Exports an AP2 artifact with execution_hash for chain provenance. Consumes upstream artifacts from: art-186-irrbb-standardised-approach-mapper. Output feeds: art-188-irrbb-disclosure-readiness-diagnostic. Open at: https://ainumbers.co/chaingraph/art-187-irrbb-csrbb-scope-checker.html. It is categorised as a Read tool in the Ainumbers Mcp Apps MCP Server, which means it retrieves data without modifying state.
check_irrbb_csrbb_scope 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.
Register the Ainumbers Mcp Apps MCP server in PolicyLayer and add a rule for check_irrbb_csrbb_scope: 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.
check_irrbb_csrbb_scope is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the check_irrbb_csrbb_scope 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.
Set action: deny in the PolicyLayer policy for check_irrbb_csrbb_scope. 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.
check_irrbb_csrbb_scope 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.
