Low Risk

get_blockers

Call this when the user asks what is blocked, what's at risk this sprint, or what needs unblocking. Returns all blocked actions with assignee and priority.

Part of the Gantta MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents call get_blockers to retrieve information from Gantta without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though get_blockers only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

What does the get_blockers tool do? +

Call this when the user asks what is blocked, what's at risk this sprint, or what needs unblocking. Returns all blocked actions with assignee and priority.. It is categorised as a Read tool in the Gantta MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get_blockers? +

Add a rule in your Intercept YAML policy under the tools section for get_blockers. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Gantta MCP server.

What risk level is get_blockers? +

get_blockers is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit get_blockers? +

Yes. Add a rate_limit block to the get_blockers rule in your Intercept 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.

How do I block get_blockers completely? +

Set action: deny in the Intercept policy for get_blockers. 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.

What MCP server provides get_blockers? +

get_blockers is provided by the Gantta MCP server (gantta/gantta-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
