Adds two vectors together. Use this when you want to combine two vectors to\nget a resultant vector. For example, adding a movement vector to a position\nvector to get a new position.
AI agents invoke math_add_vector to trigger actions in TypeSpec 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.
This tool performs a mathematical computation (vector addition). It has no side effects on data, files, or external systems. The closest category is Execute since it runs a computation/operation rather than reading stored data. Severity is low as the blast radius of misuse is minimal — it simply returns a calculated result.

Documented attack patterns abuse exactly the kind of access math_add_vector gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and TypeSpec MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for math_add_vector:
{
"version": "1",
"default": "deny",
"tools": {
"math_add_vector": {
"limits": [
{
"counter": "math_add_vector_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}math_add_vector 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.

Adds two vectors together. Use this when you want to combine two vectors to\nget a resultant vector. For example, adding a movement vector to a position\nvector to get a new position. It is categorised as a Execute tool in the TypeSpec MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the TypeSpec MCP Server MCP server in PolicyLayer and add a rule for math_add_vector: 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 TypeSpec MCP Server. Nothing to install.
math_add_vector 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 math_add_vector 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 math_add_vector. 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.
math_add_vector is provided by the TypeSpec MCP Server MCP server (microsoft/typespec-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from TypeSpec MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
