Kundali Chart MCP Server
kundali-chart-mcp
npm
v0.5.7
Published by an unidentified publisher — no publish provenance and no public repository, so the publisher could not be verified and the source cannot be independently located.
The most comprehensive Vedic Astrology MCP server — 54 tools, Google Sign-In auth, zero setup. Works with Claude, Cursor, VS Code, Windsurf, Zed, and any MCP client.
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 − 7.5 = 93. What the published surface and source actually contain:
| Points | What was found | Category |
|---|---|---|
| −6.3 | Untrusted input concatenated into a command sink MTC-SRC-009 | injection |
| −1.2 | Hardcoded Google API key in server code MTC-SRC-008 | exfiltration |
2. Client adoption risk — 93 − 8 = 85. 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 |
| −2 | publisher verification (unlinked) — no provenance/repo link, but the shipped source was fully read |
Capability observations and info notes are shown under Findings but never scored.

Findings 4
high Shell/command execution in server code (kundali-chart-mcp.js)MTC-SRC-002
In the server's implementation (`kundali-chart-mcp.js:18`): Spawning a shell/process is command-execution capability; with unsanitized tool input it is command injection / RCE. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: { execSync } from "node:child_process"; import { createServer } from "node:http"; const __filename = fileURLToPath(impo
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.

medium Hardcoded egress to an external endpoint (kundali-chart-mcp.js)MTC-SRC-003
In the server's implementation (`kundali-chart-mcp.js:256`): A hardcoded outbound call to a fixed external host inside server code is a classic exfiltration/telemetry channel — especially paired with reads of local data. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: const response = await fetch( "https://securetoken.googleapis.com/v1/token?key=" + FIREBASE_CONFIG.apiKey, {

medium Untrusted input concatenated into a command sink (kundali-chart-mcp.js)MTC-SRC-009
In the server's implementation (`kundali-chart-mcp.js:165`): A shell/process command assembled from concatenated or interpolated values is command injection when any part is attacker-influenced — the OWASP canonical RCE flow. Verify what reaches the interpolated value. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: = "darwin") { execSync(`open "${authUrl}"`); } else if (platform === "win32") { execSync(`st

low Hardcoded Google API key in server code (kundali-chart-mcp.js)MTC-SRC-008
A hardcoded Google API key (a public Firebase/web API key) appears in `kundali-chart-mcp.js:37`. Verify whether this is a real credential; if so, remove and rotate it.
Evidence: Google API key: AIza…(redacted)
Fix: Remove the secret, rotate it, and load credentials from the environment or a secret store.

Tools 1
Each tool and what it can reach — statically extracted from the published source.

What this scan could not see
- Tools were statically extracted from the published source (1 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 2
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 |
|---|---|---|---|---|
v0.5.7 latest |
B 85/100 | 4 | 1.13.0 | 2026-09-07 |
v0.5.3 |
B 85/100 | 4 | 1.10.0 | 2026-07-25 |
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.
