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.

Security Findings (47)

  • 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.

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout ×12

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

    get_build_failure_logsfind_flaky_testsget_latest_pipeline_statusget_job_test_resultsrun_pipelinelist_followed_projectsrun_evaluation_testsrerun_workflowdownload_usage_api_datarun_rollback_pipelinelist_component_versionslist_artifacts

    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

    ⚠️Excessive Permissions ×16

    declared capabilities: network access, filesystem access

    get_build_failure_logsrun_evaluation_tests

    declared capabilities: network access

    declared capabilities: code/command execution

    list_followed_projectslist_component_versions

    declared capabilities: code/command execution, network access, filesystem access

    download_usage_api_data

    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

    ℹ️Dependency Inventory Unavailable ×17

    No metadata.dependencies or repo_url were exposed by this MCP server, and no local project manifest could be inferred from the launch command.

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-server-circleci"

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