Catalog every developer API vendor indexed by the Nextdev Agent Usability Index — Stripe, Plaid, Twilio, Persona, Adyen, AgentMail, Stytch, Skyfire, and dozens more. Returns each vendor\
AI agents call list_orgs to retrieve information from Nextdev MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a static catalog of API vendors and returns structured metadata. It performs no side effects, does not execute code, does not modify data, and does not access sensitive user data or financial systems. The blast radius of misuse is minimal: an agent could only retrieve publicly indexed vendor information to inform API recommendations.
From the tool's definition Tool description states 'Catalog every developer API vendor' and 'Returns each vendor' — indicates retrieval of indexed data with no modification, deletion, or execution. Name 'list_orgs' confirms enumeration/read pattern.
Risk signalsBulk/mass operation — affects multiple targets
Documented attack patterns abuse exactly the kind of access list_orgs gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Nextdev MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for list_orgs:
{
"version": "1",
"default": "deny",
"tools": {
"list_orgs": {}
}
}list_orgs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Catalog every developer API vendor indexed by the Nextdev Agent Usability Index — Stripe, Plaid, Twilio, Persona, Adyen, AgentMail, Stytch, Skyfire, and dozens more. Returns each vendor\. It is categorised as a Read tool in the Nextdev MCP MCP Server, which means it retrieves data without modifying state.
Register the Nextdev MCP server in PolicyLayer and add a rule for list_orgs: 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 Nextdev MCP. Nothing to install.
list_orgs is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_orgs 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 list_orgs. 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.
list_orgs is provided by the Nextdev MCP server (nextdev-labs/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
