baseline-mcp
Enables read-only interaction with Baseline irrigation controllers, including status, alarms, and historical reporting.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
baseline_whoamiValidate the session and return the logged-in user, access level, current company, and assigned controller ids.
baseline_list_companiesList the Baseline organizations (companies) this account can access. Use a companyId to scope baseline_list_controllers, or pin one via BASELINE_COMPANY_ID.
baseline_list_controllersList sites and controllers (with model, firmware, subscription, device counts) across every organization the account can access. Pass companyId to limit to one org.
baseline_get_statusLive snapshot for a controller: overall status plus per-zone and per-device status codes (Running/Done/Off/Error/etc.) with decoded sensor readings.
baseline_list_zonesZone configuration for a controller: number, name, decoder serial, enabled state, designed/learned flow, and hydrozone agronomy details.
baseline_get_alarmsActive alarms and faults for a controller (valve short circuits, flow comm failures, dial-off, empty conditions, etc.), decoded with sender device and fault type.
baseline_get_announcementsVendor proactive notifications (e.g. scheduled server-maintenance banners), as plain text.
baseline_get_reportbaseline_list_devicesEnumerate every device on a controller grouped by type (zones, flow meters, moisture/temperature/pressure sensors, master valves, pumps, rain gauges, event switches). Each entry includes the `reportingSn` to pass as deviceSn to baseline_get_history.
baseline_get_programsList watering programs for a controller with their last start/finish, duration, water used, next scheduled start/finish, and assigned zones. Sourced from the controller config.
baseline_get_livebaseline_get_historyDisclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
fast-xml-parser has an entity encoding bypass via regex injection in DOCTYPE entity names
@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
fast-xml-parser affected by numeric entity expansion bypassing all entity expansion limits (incomplete fix for CVE-2026-26278)
BASELINE_BASE_URLBASELINE_PASSWORDProvide credentials via environment variables (BASELINE_USERNAME, ).BASELINE_TIMEOUT_MSBASELINE_USERNAMEProvide credentials via environment variables (, BASELINE_PASSWORD).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
12/12 tools missing one or more hints — baseline_whoami (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); baseline_list_companies (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); baseline_list_controllers (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +9 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
Only 5/12 tool handlers declare input schemas (42%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 0/12 tool handlers wrap calls in try/catch (0%)
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.
Shell command execution
1 child_process call — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
1 critical, 5 high severity in production deps — fast-xml-parser@4.5.0 (critical), @modelcontextprotocol/sdk@1.12.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
