n8n MCP Community

Generate n8n's instance-level security audit. Use it for an explicitly approved instance audit; use n8n_introspect for deterministic analysis of one workflow without this side effect. Unsafe mode and exact confirmation are required; returns an untrusted report.

List bounded metadata for installed n8n community packages. Use it for package inventory; use n8n_list_node_types for types observed in workflows. It never installs, updates, or removes packages and returns at most 100 untrusted records plus truncation counts.

Create one credential from a supported public schema. Use n8n_credentials_schema first; use n8n_credentials_update when the credential already exists. Secret values belong only in input and are excluded from logs and output; returns metadata only.

Permanently delete one stored credential, which can break referencing workflows. Use n8n_credentials_usage first; use n8n_credentials_update when replacement is sufficient. Unsafe mode and exact confirmation are required; returns the ID with deleted=true.

Get public metadata for one stored credential. Use it when the ID is known; use n8n_credentials_list for discovery and n8n_credentials_schema for type fields. Returns validated metadata without retrieving secret values.

List one page of credential metadata through the endpoint supported from n8n Community 2.30.5. Use it for discovery; use n8n_credentials_get when the ID is known. Returns metadata and a cursor, never credential values.

Get the Public API field schema for one credential type. Use it before n8n_credentials_create or replacement-data updates; use n8n_credentials_get for stored metadata. Returns schema fields supplied by n8n, never stored secret values.

Test one stored credential by allowing n8n to contact its external service. Use n8n_credentials_get for metadata-only inspection; do not call this when network contact is unwanted. Unsafe mode and exact confirmation are required; returns a bounded value-free status.

Update selected metadata or values on an existing credential. Use n8n_credentials_schema for data fields; use n8n_credentials_create for a new credential. Supply at least one field, and data when changing type; returns metadata without secret values.

Scan one bounded workflow page for exact references to a credential ID. Use it before n8n_credentials_update or deletion; use n8n_credentials_get for metadata only. Continue nextCursor for full coverage; returns matching workflows/nodes and unresolved counts.

Permanently delete one saved execution. Use it only after n8n_executions_get confirms the target and retained history is no longer needed; inspection alone should use the read tools. Unsafe mode and exact confirmation are required; returns deleted=true.

Get metadata for one saved execution. Use it when the ID is known; use n8n_executions_list to discover or filter executions. Returns status, timing, workflow identity, and data presence without exposing node inputs or outputs.

List one page of saved execution metadata, optionally filtered by status or workflow. Use it for discovery and bounded triage; use n8n_executions_get when an execution ID is known. Returns metadata and a cursor, never raw workflow payload values.

Retry one eligible saved execution, which may repeat external side effects. Use it only after n8n_executions_get review; use n8n_executions_stop for a currently running execution. Unsafe mode and exact confirmation are required; returns value-free retry metadata.

Request cancellation of one running execution without rolling back completed external effects. Use n8n_executions_get for inspection or n8n_executions_retry for an eligible saved failure. Unsafe mode and exact confirmation are required; returns stopped, already_finished, or unknown.

Return a bounded bundled reference for one of four allowlisted core n8n nodes. Use it for offline orientation; use n8n_list_node_types to inventory observed types, and official docs for other nodes. Performs no fetch and returns a title, summary, guidance, official URL, and provenance.

Perform a bounded same-origin health check against the configured n8n instance. Use it for reachability only; use an authenticated read tool such as n8n_workflows_list to validate API-key access. Returns ok=true and the HTTP status, not API capability.

Get n8n's official aggregate insights summary for an optional ISO 8601 range. Use it for instance aggregates when the Community endpoint exists; use n8n_introspect for one workflow's diagnostics. Returns totals, failures, failure rate, time saved, and runtime aggregates.

Inspect one workflow and bounded saved executions with deterministic local rules. Use quick for triage and deep for limited redacted details; use n8n_audit_generate for instance security or n8n_workflows_get for raw structure. Never executes; returns findings and coverage.

List node types observed across bounded workflow pages. Use it for usage inventory, not installed-package availability; use n8n_get_node_docs for bundled references or n8n_community_packages_list for package metadata. Returns counts and scan coverage.

Search one bounded workflow page locally by name, node type, or tag name. Use it for substring matching; use n8n_workflows_list for an unsearched API page. Continue nextCursor because this is not an instance-wide index; returns value-free matches and coverage state.

Create one workflow tag. Use it for a new reusable label; use n8n_tags_update when the tag already exists, and n8n_workflows_update_tags to assign it. Returns validated metadata and never assigns the new tag automatically.

Permanently delete one workflow tag. Use it only after n8n_tags_get and affected-workflow review; use n8n_tags_update when a rename is sufficient. Unsafe mode and exact confirmation are required; returns the ID with deleted=true.

Get one workflow tag by its stable ID. Use it to verify a known tag before assigning, renaming, or deleting it; use n8n_tags_list for discovery. Returns validated tag metadata without changing workflows.

List one page of workflow tags. Use it to discover stable tag IDs; use n8n_tags_get instead when the ID is already known. Returns validated tag metadata and an optional cursor for the next page.

Rename one workflow tag without changing its stable ID or assignments. Use it for an existing tag; use n8n_tags_create for a new label and n8n_workflows_update_tags for assignments. Returns validated updated metadata.

Update one validated mutable property on one workflow node while preserving the rest. Use it instead of n8n_workflows_update for a single-node change; use the full update for top-level or multi-node edits. Requires version/risk guards and returns the path plus non-atomic risk.

Invite one non-owner user by email with a supported global role. Use n8n_users_get first when the address may already exist; this tool is not an update operation. Unsafe mode and exact email confirmation are required; returns delivery state without an acceptance URL.

Delete one API-eligible user; ownership handling follows n8n's Public API. Use it only after n8n_users_get verifies the target and consequences; read tools should be used for inspection. Unsafe mode and exact confirmation are required; returns deleted=true.

Get one user by stable ID or exact email address. Use it for targeted verification before an administrative action; use n8n_users_list for discovery. Returns validated identity, role, and account state without changing the user.

List one page of users visible through the n8n Public API. Use it for discovery; use n8n_users_get when a stable ID or exact email is already known. Returns validated user metadata and an optional next-page cursor.

Activate one workflow so production triggers can accept future events. Use it only after n8n_workflows_get review; use n8n_workflows_deactivate to stop future triggers. Unsafe mode and exact confirmation are required; returns allowlisted state metadata.

Archive one workflow without deleting it. Use it instead of n8n_workflows_delete when reversible lifecycle removal is required; use n8n_workflows_deactivate only to stop triggers. Unsafe mode and exact confirmation are required; returns archive state.

Create one workflow from a complete validated definition. Use it for a new workflow; use n8n_workflows_update for an existing workflow and n8n_workflows_activate separately for triggers. Validates the graph and returns a projection without pin/static values.

Deactivate one workflow's production triggers without deleting saved data or stopping current work. Use n8n_workflows_activate to reverse this state or n8n_workflows_archive for lifecycle removal. Unsafe mode and exact confirmation are required; returns state metadata.

Permanently delete one workflow and its saved definition. Use n8n_workflows_archive when reversible removal is sufficient and n8n_workflows_get for inspection. Unsafe mode and exact target confirmation are required; returns the ID with deleted=true.

Compare one retained workflow version with another or current state. Use it for value-free review; use n8n_workflows_get_version when raw historical structure is needed. Returns counts, coverage, and up to 200 changes; unavailable historical fields are explicit.

Get one current workflow by stable ID for inspection or reviewed editing. Use n8n_workflows_get_version for retained history or n8n_workflows_list for discovery. Returns structure, state, settings, and presence flags; pin/static values are always withheld.

List the tags currently assigned to one workflow. Use it before n8n_workflows_update_tags when assignments must be preserved; use n8n_tags_list to discover all available tags. Returns a bounded validated collection with exact truncation counts.

Get one retained historical workflow snapshot. Use it when exact historical nodes/connections are needed; use n8n_workflows_get for current state or n8n_workflows_diff for value-free comparison. Returns validated identity and structure, subject to Community retention.

List one page of workflows visible to the configured API key. Use it for unsearched discovery; use n8n_search_workflows for local substring matching or n8n_workflows_get when the ID is known. Returns projected workflows and a cursor, never pin/static values.

Restore one archived workflow without activating it. Use it to reverse n8n_workflows_archive; call n8n_workflows_activate separately only if triggers should resume. Unsafe mode and exact confirmation are required; returns archive state.

Update selected top-level workflow fields while preserving omitted writable fields. Use n8n_update_node for one node property and n8n_workflows_update_tags for tag assignments. Requires the current versionId, performs a non-atomic full PUT, and returns the confirmed projection.

Replace the complete tag assignment for one workflow; this is not a merge. Use n8n_workflows_get_tags first to preserve existing assignments and n8n_tags_create for a missing tag; an empty array clears all tags. Returns n8n's validated assignment.
