WHAT IT DOES

What publish_fund_nav_head does on Ainumbers Mcp Apps

AI agents use publish_fund_nav_head 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 publish_fund_nav_head 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 publish_fund_nav_head, this is the rule to start with:

publish_fund_nav_head Rate-limited

publish_fund_nav_head 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 publish_fund_nav_head

What does the publish_fund_nav_head tool do? +

Publish Fund NAV Head: OpenChainGraph compute node (attestation_mandate). 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-373-recompute-fund-nav. Open at: https://ainumbers.co/chaingraph/art-659-publish-fund-nav-head.html FV-status (published/proven/still-trusted for this spec): /fv-status/8498d0819c941fdb731f9e10f5d93ee929026919cb111a42149821b48b5ac180.json — a snapshot, not a subscription; this receipt verifies offline regardless of whether that file is ever fetched. Output schema: call describe_tool("publish_fund_nav_head"). It is categorised as a Write tool in the Ainumbers Mcp Apps MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does publish_fund_nav_head accept? +

publish_fund_nav_head 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 publish_fund_nav_head? +
