Every server starts at 100. These are the exact deductions the deterministic engine applied — each one reproducible, none of it an opinion or an LLM's guess:
| Points | What was found | Category |
|---|---|---|
| −23.1 | Dynamic evaluation of a non-literal value ×2 MTC-SRC-010 | injection |
| −6.7 | Possible combosquat of mcp ×4 MTC-SUP-006 | supply-chain |
| −2.1 | Package has no source repository MTC-SUP-011 | supply-chain |
Capability observations and info notes are shown under Findings but never scored.

Findings 10
high Dynamic evaluation of a non-literal value (wasm-bundler/sprigr_browser_bg.js)MTC-SRC-010
In the server's implementation (`wasm-bundler/sprigr_browser_bg.js:370`): Evaluating a runtime value as code (rather than a fixed literal) executes whatever reaches it — a direct RCE primitive, and almost never necessary in legitimate code. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: new Function(
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 Dynamic code execution in server code (wasm-bundler/sprigr_browser_bg.js)MTC-SRC-001
In the server's implementation (`wasm-bundler/sprigr_browser_bg.js:370`): Evaluating strings as code is the most direct RCE primitive; if any tool input reaches it, the server executes attacker-chosen code. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.

medium Dynamic module load from a non-literal (dist/index.js)MTC-SRC-005
In the server's implementation (`dist/index.js:39`): Loading a module chosen at runtime (from a variable) can pull in and run attacker-influenced code paths. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: import(jsPath)

medium Possible combosquat of mcpMTC-SUP-006
"@sprigr/mcp-server" is "mcp" with a decorative suffix — a common combosquat pattern.
Fix: Confirm you meant "mcp". Install packages only from their documented, official name.
Location: package @sprigr/mcp-server
medium Possible combosquat of @playwright/mcpMTC-SUP-006
"@sprigr/mcp-server" is "@playwright/mcp" with a decorative suffix — a common combosquat pattern.
Fix: Confirm you meant "@playwright/mcp". Install packages only from their documented, official name.

medium Possible combosquat of @stripe/mcpMTC-SUP-006
"@sprigr/mcp-server" is "@stripe/mcp" with a decorative suffix — a common combosquat pattern.
Fix: Confirm you meant "@stripe/mcp". Install packages only from their documented, official name.
Location: package @sprigr/mcp-server
medium Possible combosquat of @browsermcp/mcpMTC-SUP-006
"@sprigr/mcp-server" is "@browsermcp/mcp" with a decorative suffix — a common combosquat pattern.
Fix: Confirm you meant "@browsermcp/mcp". Install packages only from their documented, official name.
Location: package @sprigr/mcp-server
low Package has no source repositoryMTC-SUP-011
"@sprigr/mcp-server" declares no repository URL, so its published artifact cannot be compared against reviewable source.
Fix: Prefer packages that link to public, reviewable source.

What this scan could not see
- No tools were enumerated, so prompt-injection, capability and toxic-flow analysis had no tool surface to inspect. To grade a package’s real runtime tools, 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 |
|---|---|---|---|---|
v1.16.0 latest |
D 68/100 | 10 | 1.5.0 | 2026-07-22 |
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.
