Risk Summary

Block in Production

Excessive Permissions + Supply Chain CVEs risk is significant. Avoid using this in production agents.

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

Recommended action: This tool should stay disabled in production agents until the flagged risks are fixed and the scan is clean.

  • HighAS-002

    ⚠️Excessive Permissions ×15

    tool declares exec permission

    create_prompt_templatelist_followed_projectsrun_evaluation_testsdownload_usage_api_datalist_component_versions

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

  • HighAS-004

    📦Supply Chain CVEs (OSV) ×17

    GO-2026-5024 in golang.org/x/[email protected]: Invoking integer overflow in NewNTUnicodeString in golang.org/x/sys/windows (upgrade to 0.44.0)

    Fix: Upgrade or replace the vulnerable dependency. Pin all dependency versions and enable automated CVE scanning (Dependabot or OSV Scanner).

  • HighAS-003

    🔀Scope Mismatch ×2

    tool name "list_followed_projects" implies read-only operation but declares exec permission

    list_followed_projects

    tool name "list_component_versions" implies read-only operation but declares exec permission

    list_component_versions

    Fix: Ensure tool names, descriptions, and permission declarations are internally consistent. Use explicit naming conventions that fully reflect actual capabilities.

  • MediumAS-002

    ⚠️Excessive Permissions ×6

    tool declares fs permission

    config_helpercreate_prompt_templaterun_evaluation_testsdownload_usage_api_datafind_underused_resource_classesanalyze_diff

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

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout ×13

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

    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.

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 circleci-public-mcp-server-circleci"

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