Risk Summary

Needs Approval

Excessive Permissions plus Supply Chain CVEs raises enough risk that this tool should not be auto-trusted.

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

Recommended action: Keep this tool behind manual approval and avoid unattended runs until the risky capabilities are narrowed or removed.

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

Security Findings (19)

  • HighAS-002

    ⚠️Excessive Permissions ×4

    tool declares network permission

    clinicaltrials_search_studiesclinicaltrials_get_study_recordclinicaltrials_get_study_countclinicaltrials_get_study_results

    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) ×7

    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)

    clinicaltrials_search_studiesclinicaltrials_get_study_recordclinicaltrials_get_study_countclinicaltrials_get_field_valuesclinicaltrials_get_field_definitionsclinicaltrials_get_study_resultsclinicaltrials_find_eligible

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

  • MediumAS-002

    ⚠️Excessive Permissions ×3

    tool declares db permission

    clinicaltrials_get_study_countclinicaltrials_get_field_definitions

    tool declares fs permission

    clinicaltrials_get_field_definitions

    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-002

    ⚠️Excessive Permissions

    clinicaltrials_search_studies:input schema exposes 18 properties (threshold: 10)

    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 ×4

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

    clinicaltrials_search_studiesclinicaltrials_get_study_recordclinicaltrials_get_study_countclinicaltrials_get_study_results

    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 cyanheads-clinicaltrialsgov-mcp-server"
