Suggest where to add links between sections
AI agents use suggest_cross_references to create or update resources in Claude Writer's Aid MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claude Writer's Aid MCP environment.
This tool suggests insertions of cross-reference links within a manuscript, which constitutes creating/modifying document content reversibly. Links can be added or removed without permanent data loss, placing it firmly in the Write category rather than Read (it modifies, not just retrieves) or Execute (it does not run arbitrary code or external operations).
From the tool's definition Tool name 'suggest_cross_references' and description 'Suggest where to add links between sections' indicates modification of document structure by adding hyperlinks to markdown content.
Documented attack patterns abuse exactly the kind of access suggest_cross_references gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Claude Writer's Aid MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for suggest_cross_references:
{
"version": "1",
"default": "deny",
"tools": {
"suggest_cross_references": {
"limits": [
{
"counter": "suggest_cross_references_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}suggest_cross_references 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.
