Merge multiple CDPs into one — builds an unsigned transaction (CBOR hex) for client-side signing
Part of the Indigo Protocol MCP server.
Free to start. No card required.
AI agents use merge_cdps to create or modify resources in Indigo Protocol MCP. 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 merge_cdps 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 Indigo Protocol MCP.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access merge_cdps 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.
Merge multiple CDPs into one — builds an unsigned transaction (CBOR hex) for client-side signing. It is categorised as a Write tool in the Indigo Protocol MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Indigo Protocol MCP server in PolicyLayer and add a rule for merge_cdps: 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 Indigo Protocol MCP. Nothing to install.
merge_cdps 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 merge_cdps 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 merge_cdps. 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.
merge_cdps is provided by the Indigo Protocol MCP server (indigoprotocol/indigo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
