n8n MCP Agent

list-workflows

Lists all workflows in an n8n instance using a client ID from init-n8n, enabling users to view and manage available automations.

Instructions

List all workflows from n8n. Use after init-n8n to see available workflows. IMPORTANT: Arguments must be provided as compact, single-line JSON without whitespace or newlines.

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Adds important formatting instruction about compact JSON arguments; no annotations present, so description compensates with behavioral detail beyond schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences front-loading purpose and usage, with no wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Missing description of return value structure (e.g., list of workflow objects) and no output schema; adequate for simple tool but incomplete for agent to fully understand output.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and description only repeats schema's 'Client ID from init-n8n', adding no new meaning beyond what schema already provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clear statement 'List all workflows from n8n' with specific verb and resource, distinguishing it from single-workflow retrieval tools like get-workflow.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly says 'Use after init-n8n to see available workflows', providing clear context for when to use it, though no exclusions or alternatives are mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
