// key findings
✅
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
✅
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.
🔐
You'll be asked for 2 credentials: OPENCTI_TOKEN, MCP_API_KEY
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
// environment variables
To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.
configOPENCTI_CLIENT_PYTHON_PATH
configOPENCTI_URLYes Base URL of the OpenCTI instance, for example http://localhost:4000
🔐 secretOPENCTI_TOKENYes OpenCTI API bearer token

configMCP_TRANSPORTNo stdio stdio or sse
configMCP_SSE_PORTNo 8000 Bind port for SSE transport

🔐 secretMCP_API_KEYRequired for SSE unless explicitly disabled Bearer token required for SSE HTTP requests
configLOG_LEVELNo info Python log level
configMCP_SSE_HOSTNo 127.0.0.1 Bind host for SSE transport
configMCP_DOTENV_PATHyou may load one explicitly trusted dotenv file by setting to
configMCP_TENANTS_JSONNo unset JSON object of additional routable tenants keyed by tenant id. Each entry must define opencti_url, opencti_token, and may override ssl_verify. Multi-tenant routing is SSE-only.
configMCP_COORDINATION_BACKEND_FACTORYNo unset Optional module:callable import path that returns a CoordinationBackends bundle for externally managed audit, quota, and idempotency storage.
configMCP_TRUSTED_PROXY_SOURCESNo 127.0.0.1,::1 Comma-separated proxy source IPs or CIDR ranges allowed to supply forwarded client headers when MCP_TRUST_PROXY_HEADERS=true. At least one source is required when enabled.
configMCP_IDEMPOTENCY_BACKENDNo memory memory for process-local replay protection or sqlite for restart-safe durable replay protection.
configMCP_IDEMPOTENCY_SQLITE_PATHRequired when MCP_IDEMPOTENCY_BACKEND=sqlite Absolute path to the SQLite idempotency database file.
configMCP_OBSERVABILITY_BACKENDNo memory memory for process-local audit and quota state or sqlite for restart-safe, cross-process observability state.
configMCP_OBSERVABILITY_SQLITE_PATHRequired when MCP_OBSERVABILITY_BACKEND=sqlite Absolute path to the SQLite observability database file.

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

71/71 tools missing one or more hints — create_incident_case (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); create_rfi (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); lookup_case (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +68 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tool inputs are validated

68/71 tool handlers declare input schemas (96%)

Declare an inputSchema with zod/joi/yup on every tool definition.

Tool handlers catch errors

66/71 tool handlers wrap calls in try/catch (93%)

Wrap each tool handler body in try/catch and return a structured error response.

Tests exist

No test files found

Add tests that exercise each declared tool.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
