Push YAML changes to a FlutterFlow project. IMPORTANT: Always call validate_yaml first to check for errors before updating. For best results, call get_editing_guide before writing YAML to get the correct workflow and schema documentation.
AI agents use update_project_yaml to create or update resources in Community Ff — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Community Ff environment.
This tool creates or modifies project configuration data reversibly through YAML changes. While it affects application behavior, the changes are reversible (can be overwritten or reverted) and do not permanently destroy data or trigger financial transactions, placing it firmly in Write category.
From the tool's definition Tool name 'update_project_yaml' and description 'Push YAML changes to a FlutterFlow project' indicate modification of project configuration data. The description explicitly advises validating before updating, confirming this modifies existing project state.
Documented attack patterns abuse exactly the kind of access update_project_yaml gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Community Ff, and nothing reaches the server without passing your rules. This is the rule we recommend for update_project_yaml:
{
"version": "1",
"default": "deny",
"tools": {
"update_project_yaml": {
"limits": [
{
"counter": "update_project_yaml_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_project_yaml stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

For best results, call get_editing_guide before writing YAML to get the correct workflow and schema documentation. It is categorised as a Write tool in the Community Ff MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Community Ff MCP server in PolicyLayer and add a rule for update_project_yaml: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Community Ff. Nothing to install.
update_project_yaml is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update_project_yaml rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for update_project_yaml. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
update_project_yaml is provided by the Community Ff MCP server (mohn93/ff-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Community Ff, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
