Risk Summary

Safe With Normal Controls

Excessive Permissions is the main signal, but overall risk remains within an acceptable range.

Potential impact: The agent may gain overly broad access to files, network, databases, or execution capabilities.

Recommended action: No high-risk findings were detected in this scan, but you should still apply least-privilege defaults and rescan after changes.

Suggested policy: keep this tool behind manual approval, do not allow unattended runs, and re-scan after narrowing risky permissions.

    Fix: The set of tools exposed by this server changed between scans of the same version — a sign the package was silently updated without a version bump. Audit the changelog and all tool definitions before trusting this server. Pin to a specific commit hash rather than a floating version tag.

  • LowAS-011

    ℹī¸Missing Rate-Limit / Timeout ×8

    tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration

    search_messages_globallyget_messagessend_messageedit_messagefind_chatsget_chat_infosend_message_to_phoneinvoke_mtproto

    Fix: Declare explicit rate-limit, timeout, and retry configuration for all network and execution tools. Implement exponential back-off and surface resource state to the calling agent.

  • InfoAS-002

    ⚠ī¸Excessive Permissions ×8

    declared capabilities: network access, database access

    search_messages_globallyget_messagesfind_chats

    declared capabilities: network access, filesystem access

    send_messageget_chat_infosend_message_to_phone

    declared capabilities: network access

    edit_message

    declared capabilities: network access, HTTP requests

    invoke_mtproto

    Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.

  • InfoAS-014

    ℹī¸Dependency Inventory Unavailable ×8

    Tool did not expose metadata.dependencies or repo_url, so supply-chain coverage is limited.

    Fix: Review and remediate the identified issue.

Scan this tool yourself

Reproduce this audit locally, integrate into CI, or let your agent audit its own tools.

Install once, then scan any MCP server:

$ curl -sfL https://raw.githubusercontent.com/AgentSafe-AI/tooltrust-scanner/main/install.sh | bash
$ tooltrust-scanner scan --server "npx -y mcp-telegram"

Adjust the package name if your npm registry name differs from the tool ID. View source
