      The server is live and answers an RFC 9728 challenge. tools/list is auth-gated, so the
      tool table below was read from Ironfang's published MCP reference rather than from live
      introspection - names, scopes and credit costs are the provider's own; inputSchemas
      require an authenticated tools/list.

reserved_tools:
  note: >-
    Ironfang documents nine auditwolf.* tools on the same endpoint, marked "Not yet available"
    pending the Auditwolf commercial release. They are not listed above because they are not
    live and they belong to a sibling product, not to Renderwolf.
resources:
  - uri: 'ironfang://connection'
    returns: The connection summary.
  - uri: 'ironfang://renderwolf/jobs/{job_id}'
    returns: The job envelope.
  - uri: 'ironfang://renderwolf/jobs/{job_id}/result'
    returns: Result metadata with a freshly signed link; marked non-cacheable.
  - uri: 'ironfang://renderwolf/templates/{template_id}'
    returns: Template metadata.
agent_safety:
  tool_hints: >-
    Every tool carries readOnlyHint, destructiveHint, idempotentHint and openWorldHint plus
    namespaced metadata naming its scope, product, credit behaviour and risk.
  spend_cap: 'connection budget = max(25, 10% of the plan monthly credits), capped by remaining allowance, per billing period'
  budget_exhausted_code: mcp_budget_exhausted
  input_policy: >-
    Strict JSON Schema objects - unknown fields rejected, every string/size/duration bounded.
    Rendering tools take a public URL or bounded raw HTML and refuse cookies, authorization
    headers, custom request headers, proxy settings, scripts to execute and private network targets.
  result_policy: >-
    Results are durable jobs, not bytes in the conversation. Hosted 24 hours, fetched through
    15-minute signed links. PDFs, clips and full-page images are never returned inline.
  token_isolation: >-
    The MCP token is audience-bound to the MCP endpoint; products reject it. Each product call
    uses a separate two-minute delegated token.
