AI agents use save_claim to create or modify resources in Valuein — SEC EDGAR Fundamentals & Smart-Money Data. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call save_claim repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Valuein — SEC EDGAR Fundamentals & Smart-Money Data.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access save_claim gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Persist a single falsifiable, evidence-backed CLAIM — the atomic unit of the research graph. Use this for each discrete assertion an analysis produces (e.g. 'NVDA gross margin stays above 70% through FY2026'), then compose claims into a thesis with link_claim_to_thesis. Claims are scored independently of theses, so claim accuracy is tracked as its own track record. Pick claim_type by HOW it's judged, not what it's about: assertion = true now, checked against data; prediction = resolves at horizon_days via verifiable_condition; judgment = qualitative, not auto-scored. Use tags for the topic (financial, valuation, macro, …). Set eval_mode: 'auto' + a verifiable_condition for deterministic grading, else 'agent'/'manual'. Tier: all paid + free tiers (sample rejected — guest has no customerId). Verifiable claims must cite evidence.. It is categorised as a Write tool in the Valuein — SEC EDGAR Fundamentals & Smart-Money Data MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Valuein — SEC EDGAR Fundamentals & Smart-Money Data MCP server in PolicyLayer and add a rule for save_claim: 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 Valuein — SEC EDGAR Fundamentals & Smart-Money Data. Nothing to install.
save_claim is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the save_claim 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 save_claim. 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.
save_claim is provided by the Valuein — SEC EDGAR Fundamentals & Smart-Money Data MCP server (https://mcp.valuein.biz/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
