Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default

XENDIT_ALLOWED_ACCOUNTSIf you enable disbursements, you must also set the four safety gates (XENDIT_MAX_DISBURSEMENT_AMOUNT, XENDIT_MAX_DAILY_AMOUNT, , XENDIT_APPROVAL_CODE) or the server will refuse to start.XENDIT_ALLOW_LIVEno Set to true to allow live/production keys (prefixes xnd_production_, iluma_production_, sk_live_). Refused by default.XENDIT_API_BASEXENDIT_API_KEYyes Test or live API keyXENDIT_APPROVAL_CODEIf you enable disbursements, you must also set the four safety gates (XENDIT_MAX_DISBURSEMENT_AMOUNT, XENDIT_MAX_DAILY_AMOUNT, XENDIT_ALLOWED_ACCOUNTS, ) or the server will refuse to start.XENDIT_DEBUGXENDIT_ENABLE_DISBURSEMENTSno Set to true to enable disbursement tools (money-movement). Disabled by default.XENDIT_ENABLE_INVOICE_MUTATIONSno Set to true to enable create_invoice, expire_invoice, and the create_payment_link prompt. Disabled by default for safer read-only behavior.XENDIT_ENABLE_LEGACY_ONE_SHOT_DISBURSEMENTno Set to true only if you intentionally want the old create_disbursement one-shot tool. Disabled by default.XENDIT_MAX_DAILY_AMOUNTIf you enable disbursements, you must also set the four safety gates (XENDIT_MAX_DISBURSEMENT_AMOUNT, , XENDIT_ALLOWED_ACCOUNTS, XENDIT_APPROVAL_CODE) or the server will refuse to start.XENDIT_MAX_DISBURSEMENT_AMOUNTIf you enable disbursements, you must also set the four safety gates (, XENDIT_MAX_DAILY_AMOUNT, XENDIT_ALLOWED_ACCOUNTS, XENDIT_APPROVAL_CODE) or the server will refuse to start.XENDIT_PREPARE_TTL_SECONDSno How long a prepared disbursement token stays valid. Defaults to 300, max 86400.Tool annotations
13/14 tools have annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
14/14 tools missing one or more hints — get_workspace_mode (missing: destructiveHint, idempotentHint, openWorldHint); guided_setup (missing: destructiveHint, idempotentHint, openWorldHint); get_balance (missing: destructiveHint, idempotentHint, openWorldHint), +11 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
13/14 tool handlers declare input schemas (93%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
12/14 tool handlers wrap calls in try/catch (86%)
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.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
