Unblock a blocked job in a build
Allows blocked deployment to proceed
Part of the Buildkite MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents invoke unblock_job to trigger processes or run actions in Buildkite. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
unblock_job can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

unblock_job is one of the high-risk operations in Buildkite. For the full severity-focused view — only the high-risk tools with their recommended policies — see the breakdown for this server, or browse all high-risk tools across every MCP server.
Unblock a blocked job in a build. It is categorised as a Execute tool in the Buildkite MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Add a rule in your Intercept YAML policy under the tools section for unblock_job. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Buildkite MCP server.
unblock_job is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the unblock_job 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.
Set action: deny in the Intercept policy for unblock_job. 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.
unblock_job is provided by the Buildkite MCP server (@buildkite/buildkite-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
