Risk Summary

Safe With Normal Controls

Dep Visibility is the main signal, but overall risk remains within an acceptable range.

Potential impact: This finding indicates the tool should be reviewed before it is trusted.

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.

  • HighAS-012

    🔄Tool Drift

    Tool set changed silently at v0.15.1: 21 tool(s) added, 15 tool(s) removed without a version bump.

    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.

  • HighAS-003

    🔀Scope Mismatch ×2

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

    get_job_logs

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

    get_orb_source

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

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout ×12

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

    download_usage_dataget_deploy_componentget_deploy_environmentget_jobget_job_logsget_orbget_orb_sourceget_runget_workflowlist_artifactslist_job_testsvalidate_config

    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-014

    ℹ️Dependency Inventory Unavailable ×22

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

    Fix: Review and remediate the identified issue.

  • InfoAS-002

    ⚠️Excessive Permissions ×14

    declared capabilities: network access, filesystem access

    download_usage_datalist_artifacts

    declared capabilities: network access

    get_deploy_componentget_jobget_orbget_runget_workflowvalidate_config

    declared capabilities: network access, environment variables

    get_deploy_environment

    declared capabilities: code/command execution, network access

    get_job_logsget_orb_source

    declared capabilities: environment variables

    list_deploy_component_versions

    declared capabilities: HTTP requests

    list_job_tests

    declared capabilities: filesystem access

    me

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

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
