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.
n8n_list_workflowsList all workflows. Optionally filter by active status and limit results.
n8n_get_workflowRetrieve a workflow by ID, including nodes, connections and settings.
n8n_create_workflowCreate a new workflow. Provide the workflow JSON (name, nodes, connections, settings).
n8n_update_workflown8n_delete_workflowPermanently delete a workflow by ID.
n8n_activate_workflowActivate a workflow for production. Requires at least one trigger node.
n8n_deactivate_workflowDeactivate a workflow (stops listening for triggers).
n8n_execute_workflowTrigger a workflow execution. Optionally send input data.
n8n_get_workflow_tagsList all tags associated with a specific workflow.
n8n_update_workflow_tagsReplace all tags on a workflow. Send an array of tag IDs.
n8n_list_executionsList workflow executions. Filter by workflowId, status, limit and cursor.
n8n_get_executionGet the status and result data of a specific execution.
n8n_delete_executionPermanently delete an execution record by ID.
n8n_list_datatablesList data tables with optional filtering, sorting and pagination.
n8n_create_datatableCreate a data table with typed columns (string, number, boolean, date, json).
n8n_get_datatableRetrieve metadata (columns, name, ID) of a data table.
n8n_get_datatable_rowsn8n_insert_datatable_rowsInsert one or more rows. Each row is an object with column names as keys.
n8n_update_datatable_rowsUpdate rows matching a filter. Conditions: eq, neq, like, ilike, gt, gte, lt, lte.
n8n_upsert_datatable_rowUpdate a row if it exists (by filter) or insert a new one.
n8n_delete_datatable_rowsDelete rows matching a filter. The filter is required (JSON string).
n8n_list_tagsList all tags in the n8n instance.
n8n_get_tagRetrieve a tag by ID.
n8n_create_tagCreate a new tag with the given name.
n8n_update_tagRename an existing tag.
n8n_delete_tagDelete a tag by ID. This does not affect workflows that used this tag.
n8n_list_credentialsList all credentials (names and types only — data is redacted).
n8n_create_credentialCreate a new credential. Use n8n_get_credential_schema to discover the required fields for a type.
n8n_delete_credentialPermanently delete a credential by ID.
n8n_get_credential_schemaGet the JSON schema for a credential type, showing required and optional fields.
n8n_list_usersList all users in the n8n instance (requires owner role).
n8n_get_userRetrieve a user by ID or email.
n8n_delete_userDelete a user by ID (requires owner role). Workflows owned by this user must be transferred first.
n8n_list_variablesList all environment variables stored in n8n.
n8n_create_variableCreate a new environment variable in n8n (key-value pair).
n8n_delete_variableDelete an environment variable by ID.
n8n_list_projectsList all projects (Enterprise feature).
n8n_create_projectCreate a new project (Enterprise feature).
n8n_update_projectRename an existing project (Enterprise feature).
n8n_delete_projectDelete a project by ID (Enterprise feature).
n8n_generate_auditn8n_health_checkCheck connectivity to the n8n instance and verify the API is reachable.
n8n_trigger_webhookDisclosed 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

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
43/43 tools missing one or more hints — n8n_list_workflows (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); n8n_get_workflow (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); n8n_create_workflow (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +40 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.
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 2 high severity in production deps — @modelcontextprotocol/sdk@1.25.0 (high), @modelcontextprotocol/sdk@1.25.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
