start_ingest_job · Sfgraph MCP: Risk & Policy

WHAT IT DOES

What start_ingest_job does on Sfgraph

AI agents invoke start_ingest_job to trigger actions in Sfgraph. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why start_ingest_job needs a policy

start_ingest_job triggers real processes with real consequences. An agent gone sideways doesn't fire it once — it starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

Verdict

start_ingest_job Rate-limited

start_ingest_job stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about start_ingest_job

What does the start_ingest_job tool do? +

RETURNS INSTRUCTIONS ONLY. The MCP server does NOT run ingest workers. To actually ingest, run. It is categorised as a Execute tool in the Sfgraph MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on start_ingest_job? +

Register the Sfgraph MCP server in PolicyLayer and add a rule for start_ingest_job: 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 Sfgraph. Nothing to install.

What risk level is start_ingest_job? +

start_ingest_job is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit start_ingest_job? +

Yes. Add a rate_limit block to the start_ingest_job 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.

How do I block start_ingest_job completely? +

Set action: deny in the PolicyLayer policy for start_ingest_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.

What MCP server provides start_ingest_job? +

start_ingest_job is provided by the Sfgraph MCP server (ryanstark24/sfgraph). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
