WHAT IT DOES

What set does on ResilientDB MCP Server

AI agents use set to create or update resources in ResilientDB MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ResilientDB MCP Server environment.

WHY IT NEEDS A POLICY

Why set needs a policy

The tool creates or modifies data (key-value pairs) in a blockchain system. This is reversible (via subsequent set operations or other write commands) rather than destructive, and does not execute arbitrary code, trigger financial transactions, or perform reads.

From the tool's definition Tool name 'set' and description 'Stores a key-value pair in ResilientDB using HTTP REST API' indicates data creation/modification.

Verdict

set Rate-limited

set 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 set

What does the set tool do? +

Stores a key-value pair in ResilientDB using HTTP REST API (Crow server on port 18000). It is categorised as a Write tool in the ResilientDB MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on set? +

Register the ResilientDB MCP Server MCP server in PolicyLayer and add a rule for set: 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 ResilientDB MCP Server. Nothing to install.

What risk level is set? +

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

Can I rate-limit set? +

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

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

set is provided by the ResilientDB MCP Server MCP server (rahulkanagaraj786/resilientdb-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
