create_experiment · Respan MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_experiment does on Respan MCP Server

AI agents invoke create_experiment to trigger actions in Respan MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why create_experiment needs a policy

The tool not only creates an experiment (Write) but also runs it and processes a dataset, indicating active execution of operations. 'Run' and 'Processes' indicate side effects beyond simple data creation, placing this in the Execute category. Severity is high because running experiments on datasets can consume significant resources, trigger downstream operations, and affect monitoring/evaluation pipelines.

From the tool's definition "Create and run an experiment. Processes a dataset"

Verdict

create_experiment Rate-limited

create_experiment stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Respan MCP Server, so you can run agents against it safely.

FAQ

Questions about create_experiment

What does the create_experiment tool do? +

Create and run an experiment. Processes a dataset. It is categorised as a Execute tool in the Respan MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on create_experiment? +

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

What risk level is create_experiment? +

create_experiment is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit create_experiment? +

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

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

create_experiment is provided by the Respan MCP Server MCP server (respanai/respan-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
