What ode_solve does on UnClick
AI agents invoke ode_solve to trigger actions in UnClick. 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.
| Parameter | Type | Required | Description |
|---|---|---|---|
t0 | number | — | Initial time (default 0) |
y0 | number | — | Initial value y(t0) (default 1) |
steps | integer | — | Number of steps (default 100, max 10000) |
t_end | number | — | End time (default 1) |
method | string | — | Integration method (default rk4) |
expression | string | Yes | JS expression for dy/dt in terms of t and y, e.g. 't + y' |
Parameters from the server's own tool schema.
Why ode_solve is rated High
The tool accepts arbitrary JavaScript expressions and evaluates/executes them to numerically solve an ODE. This constitutes code execution, as user-supplied JS code is run on the server. Severity is medium because the blast radius depends on the sandboxing of the JS evaluation environment, but arbitrary code injection is a realistic risk.

Attacks that exploit this kind of access
The rule that runs ode_solve safely
PolicyLayer is an MCP gateway: it sits between your AI agents and UnClick, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ode_solve, this is the rule to start with:
ode_solve 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.
The button opens the PolicyLayer dashboard: create your workspace, connect UnClick, apply this rule, and every ode_solve call is checked against it from then on.
Questions about ode_solve
Solve an ordinary differential equation numerically using Euler or RK4 method. Provide the ODE as a JS expression in terms of t and y. It is categorised as a Execute tool in the UnClick MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
ode_solve accepts 6 parameters: t0, y0, steps, t_end, method, expression. Required: expression. The full parameter table on this page comes from the server's own tool schema.
Register the UnClick MCP server in PolicyLayer and add a rule for ode_solve: 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 UnClick. Nothing to install.
ode_solve is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the ode_solve 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 ode_solve. 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.
ode_solve is provided by the UnClick MCP server (@unclick/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
