Authenticate with Pega Infinity server using OAuth2 client credentials or direct access token. Stores the authentication token in session for use by other tools. This tool should be used before making API calls when you want to explicitly manage authentication.
AI agents call authenticate_pega as a supporting operation in Pega DX MCP Server workflows.
This tool performs authentication and session token management — it does not read data, write/modify records, execute code, destroy data, or move money. It establishes credentials used by other tools. However, misuse could grant an AI agent broad access to the Pega platform (hence medium severity), but the act itself is credential/session setup, which fits 'Other' best among the available categories.
From the tool's definition Authenticate with Pega Infinity server using OAuth2 client credentials or direct access token. Stores the authentication token in session for use by other tools.
Documented attack patterns abuse exactly the kind of access authenticate_pega gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Pega DX MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for authenticate_pega:
{
"version": "1",
"default": "deny",
"tools": {
"authenticate_pega": {
"limits": [
{
"counter": "authenticate_pega_rate",
"window": "minute",
"max": 60,
"scope": "grant"
}
]
}
}
}authenticate_pega gets a rate cap, and everything else on the server is denied unless you say otherwise.

Authenticate with Pega Infinity server using OAuth2 client credentials or direct access token. Stores the authentication token in session for use by other tools. This tool should be used before making API calls when you want to explicitly manage authentication. It is categorised as a Other tool in the Pega DX MCP Server MCP Server, which means it performs auxiliary operations.
Register the Pega DX MCP Server MCP server in PolicyLayer and add a rule for authenticate_pega: 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 Pega DX MCP Server. Nothing to install.
authenticate_pega is a Other tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the authenticate_pega 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 authenticate_pega. 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.
authenticate_pega is provided by the Pega DX MCP Server MCP server (marco-looy/pega-dx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Pega DX 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.
