WHAT IT DOES

What createDocumentIngestSession does on Stable Baseline

AI agents use createDocumentIngestSession to create or update resources in Stable Baseline, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Stable Baseline environment.

Parameter	Type	Required	Description
`fileName`	string	Yes	Original filename, e.g. report.pdf.
`folderId`	string	—	Optional folder to drop the document into. Must belong to projectId.
`mimeType`	string	Yes	One of: application/pdf, application/vnd.openxmlformats-officedocument.wordprocessingml.document (DOCX), text/plain, text/markdown.
`projectId`	string	Yes	Target project for the resulting document.
`sizeBytes`	number	—	Optional file size hint in bytes. Rejected up-front if it exceeds 150 MB.

Parameters from the server's own tool schema.

RISK

Why createDocumentIngestSession is rated Medium

This tool initiates document creation by setting up an upload session. While it doesn't directly delete data (would be Destructive) or execute arbitrary code (would be Execute), it does create persistent records in the system.

From the tool's definition Tool creates a new ingest session and facilitates file upload. Description explicitly states 'Mint a single-use PUT upload URL' and 'start the conversion' to create a document, which are write operations that modify the system state by adding new documents.

RECOMMENDED RULE

The rule that runs createDocumentIngestSession safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Stable Baseline, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For createDocumentIngestSession, this is the rule to start with:

createDocumentIngestSession Rate-limited

createDocumentIngestSession 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.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "createDocumentIngestSession": {
      "limits": [

          "counter": "createdocumentingestsession_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Stable Baseline, apply this rule, and every createDocumentIngestSession call is checked against it from then on.

FAQ

Questions about createDocumentIngestSession

What does the createDocumentIngestSession tool do? +

Step 1 of file ingest. Mint a single-use PUT upload URL for a large file (PDF, DOCX, plain text, or markdown — up to 150 MB). Returns { sessionId, uploadUrl, expiresAt, maxBytes }. Upload the raw bytes to uploadUrl with PUT, then call createDocumentFromUpload({ sessionId, projectId }) to start the conversion. The file is auto-deleted once the document is created. It is categorised as a Write tool in the Stable Baseline MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does createDocumentIngestSession accept? +

createDocumentIngestSession accepts 5 parameters: fileName, folderId, mimeType, projectId, sizeBytes. Required: fileName, mimeType, projectId. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on createDocumentIngestSession? +

Register the Stable Baseline MCP server in PolicyLayer and add a rule for createDocumentIngestSession: 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 Stable Baseline. Nothing to install.

What risk level is createDocumentIngestSession? +

createDocumentIngestSession is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit createDocumentIngestSession? +

Yes. Add a rate_limit block to the createDocumentIngestSession 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 createDocumentIngestSession completely? +

Set action: deny in the PolicyLayer policy for createDocumentIngestSession. 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 createDocumentIngestSession? +
