WHAT IT DOES

What export_artifact does on Ainumbers Mcp Apps

AI agents use export_artifact 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
`format`	string	Yes	Export profile. xlsx/csv/pdf/xbrl/vc implemented; vc = W3C Verifiable Credentials 2.0 (base profile, all nodes).
`artifact`	object	Yes	Full v0.4 ChainGraph artifact (policy_parameters + output_payload + execution_hash + chain).
`xbrl_taxonomy`	string	—	Required only when format="xbrl" (e.g. "eba-corep-own-funds").

Parameters from the server's own tool schema.

RISK

Why export_artifact is rated Medium

An AI agent can call export_artifact faster than any human can review: one bad instruction and it creates or modifies resources in Ainumbers Mcp Apps by the hundred, each call as confident as the last.

RECOMMENDED RULE

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

export_artifact Rate-limited

export_artifact 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 export_artifact

What does the export_artifact tool do? +

Render a verified OpenChainGraph v0.4 artifact into a chaingraph_export profile (OCG Standard §13). Generated downstream of and EXCLUDED from the execution_hash preimage — the export is a view, not a fact; verification always routes back to the canonical JSON artifact. Pass the FULL artifact you received from a compute tool (the server is stateless — there is no hash cache). Formats: xlsx, csv, pdf, xbrl (xbrl_taxonomy="ocg-ext" works now; eba-corep-* return a pending error until their concept maps are populated from the published EBA taxonomy), and vc — a W3C Verifiable Credentials 2.0 rendering (OCG §13.11, application/vc+json) available on every node; it re-states the canonical execution_hash via ocg:hashAnchor and mints no new hash/proof. readOnlyHint: true; zero PII, zero payload logging. 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 export_artifact accept? +

export_artifact accepts 3 parameters: format, artifact, xbrl_taxonomy. Required: format, artifact. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on export_artifact? +

Register the Ainumbers Mcp Apps MCP server in PolicyLayer and add a rule for export_artifact: 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 export_artifact? +

export_artifact is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit export_artifact? +

Yes. Add a rate_limit block to the export_artifact 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 export_artifact completely? +

Set action: deny in the PolicyLayer policy for export_artifact. 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 export_artifact? +

export_artifact 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.
