Ticketer MCP Server
mcp-ticketer
PyPI
v2.3.19
Published by mcp-ticketer — no publish provenance, so origin is unverified, but the source is public: the repository link below is self-declared yet readable, so you can inspect the code before adopting it.
The grade answers one question — how safe is this server for you to adopt — so it is computed in two auditable stages. Nothing below is an opinion or an LLM's guess; every line is a real term the deterministic engine applied, and the same input always yields the same number.
1. Threat score — 100 − 22 = 78. What the published surface and source actually contain:
| Points | What was found | Category |
|---|---|---|
| −22 | Hardcoded GitHub token in server code MTC-SRC-008 | exfiltration |
2. Client adoption risk — 78 − 7 = 71. Three small, subtract-only factors that reflect your risk in adopting it — a clean scan proves less on a powerful, unverified or barely-inspectable package, so the grade says so plainly:
| Points | Adoption-risk factor |
|---|---|
| −6 | capability blast radius (high) — client exposure if the model is manipulated |
| −1 | publisher verification (public source) — no provenance, but the source is public and inspectable |
| ✓ | inspection depth (source) — how much of the target the scan could see |
Grade capped: 1 confirmed high finding → grade capped at C. A hard gate overrides the point total — no amount of clean surface buys back a confirmed catastrophe.
Capability observations and info notes are shown under Findings but never scored.

Findings 14
high Reads a sensitive credential path or dumps the environment (tests/e2e/test_mcp_analysis_tools.py)MTC-SRC-006
In the server's implementation (`tests/e2e/test_mcp_analysis_tools.py:163`): Reading private keys / cloud credentials, or serializing the whole environment, is a sensitive-data source that becomes exfiltration when combined with any egress. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: dict(os.environ)
Fix: Review this call path: confirm it never receives unsanitized tool input, constrain it, or remove it. Treat a server whose code reaches these sinks as high-capability regardless of what its tools claim.

high Reads a sensitive credential path or dumps the environment (tests/e2e/test_mcp_jsonrpc.py)MTC-SRC-006

high Hardcoded GitHub token in server code (tests/cli/test_configure_gh_accounts.py)MTC-SRC-008
A live-looking GitHub token is hardcoded in `tests/cli/test_configure_gh_accounts.py:200`. Secrets in source ship to everyone who installs the package and are a direct credential leak.
Evidence: GitHub token: ghp_…(redacted)
Fix: Remove the secret, rotate it, and load credentials from the environment or a secret store.

In the server's implementation (`scripts/manage_version.py:242`): Spawning a shell/process is command-execution capability; with unsanitized tool input it is command injection / RCE.

What this scan could not see
- Tools were statically extracted from the published source (13 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".
Versions
Scan history per published version. The engine is deterministic — the same version always yields the same score, so a changed score means the package itself changed.
| Version | Score | Findings | Engine | Scanned |
|---|---|---|---|---|
v2.3.19 latest |
C 71/100 | 14 | 1.7.0 | 2026-07-23 |
Embed this score
Show this server's live Trust Score in your README, docs or website. The badge is served straight from the registry and updates automatically after every rescan — no API key needed. It links back to this page, so anyone who sees the grade can also read the findings behind it instead of taking a number on faith.
Verify this score yourself
The score above is reproducible: the same package version always yields the same result. Run it locally or over the free API — no account, no LLM, fully deterministic.
