135 tools. 55 can modify or destroy data without limits.
14 destructive tools with no built-in limits. Policy required.

Financial operations (chatMediaUploadFinalize, finalizeMediaUpload) can move real money. An agent caught in a loop could drain accounts before anyone notices.
Destructive tools (deleteAccountActivitySubscription, deleteActivitySubscription, deleteAllConnections) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.
Write operations (addChatGroupMembers, addListsMember, addUserPublicKey) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
Execute tools (initializeChatConversationKeys, initializeChatGroup, initializeMediaUpload) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.
Intercept sits between your agent and Xdevplatform/xmcp. Every tool call checked against your policy before it executes — so your agent can do its job without breaking things.
npx -y @policylayer/intercept scan -- npx -y @xdevplatform/xmcp chatMediaUploadFinalize:
rules:
- action: deny Financial tools should be explicitly enabled per use case, not open by default.
deleteAccountActivitySubscription:
rules:
- action: deny Destructive tools should never be available to autonomous agents without human approval.
addChatGroupMembers:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
chatMediaDownload:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
Yes. The Xdevplatform/xmcp server exposes 2 financial tools including chatMediaUploadFinalize, finalizeMediaUpload. Without a policy, an autonomous agent can call these with no spend caps, no rate limits, and no approval flow. Intercept lets you block financial tools by default or set per-tool rate limits.
Yes. The Xdevplatform/xmcp server exposes 12 destructive tools including deleteAccountActivitySubscription, deleteActivitySubscription, deleteAllConnections. These permanently remove resources with no undo. Intercept blocks destructive tools by default so they never reach the upstream server.
The Xdevplatform/xmcp server has 30 write tools including addChatGroupMembers, addListsMember, addUserPublicKey. Set rate limits in your policy file -- for example, rate_limit: 10/hour prevents an agent from making more than 10 modifications per hour. Intercept enforces this at the transport layer.
135 tools across 6 categories: Destructive, Execute, Financial, Other, Read, Write. 80 are read-only. 55 can modify, create, or delete data.
One line change. Instead of running the Xdevplatform/xmcp server directly, prefix it with Intercept: intercept -c xdevplatform-xmcp.yaml -- npx -y @xdevplatform/xmcp. Download a pre-built policy from policylayer.com/policies/xdevplatform-xmcp and adjust the limits to match your use case.
Starter policies available for each. Same risk classification, same one-command setup.
Set budgets, approvals, and hard limits across MCP servers.
