QGIS MCP

Batch Commands

batch_commands

Execute multiple non-destructive QGIS commands in a single request to reduce round-trips and improve efficiency.

Instructions

Execute multiple commands in a single round-trip. Each command is {"type": "<command_name>", "params": {...}}. Destructive commands (execute_code, remove_layer, delete_features, set_setting, reload_plugin) are not allowed in batch — use them individually.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
commandsYes
Behavior3/5

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

No annotations provided, so description must carry the burden. It discloses that destructive commands are not allowed but lacks details on execution order, error handling, atomicity, or side effects. Partial disclosure but not comprehensive.

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 sentences, no wasted words. Front-loaded with purpose and constraints. Efficient and clear.

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

Completeness2/5

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

No output schema or annotations. Description does not explain return value (e.g., results per command, errors). For a batch tool, this is a significant gap. Incomplete for safe usage.

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

Parameters4/5

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

Only one parameter 'commands' with 0% schema coverage. The description adds meaning by prescribing the format (type and params) beyond the schema, partially compensating for the lack of schema details.

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?

The description clearly states the tool executes multiple commands in a single round-trip and specifies the required format for each command. It effectively distinguishes itself from individual command execution.

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

Usage Guidelines5/5

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

Explicitly lists when to use batch (for multiple commands) and which commands are disallowed (destructive ones), directing to use them individually. Provides clear alternatives.

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