What findAndReplaceTextInDocument does on Stable Baseline
AI agents use findAndReplaceTextInDocument 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 |
|---|---|---|---|
find | string | Yes | Text to search for. |
replace | string | Yes | Replacement text. Empty string to delete occurrences. |
documentId | string | Yes | |
caseSensitive | boolean | — | Case-sensitive matching. Default: true. |
changeSummary | string | — | Version history summary. |
versionTimestamp | number | — | Optional optimistic-lock token from getDocument() or a previous write; validated when provided. (Alias accepted: documentVersionTimestamp.) |
Parameters from the server's own tool schema.
Why findAndReplaceTextInDocument is rated Medium
This tool modifies document content by replacing text occurrences. It is a write operation (text substitution) that is reversible in principle, though replacing every occurrence of a substring across a document could have broad impact if misused. It does not delete data irreversibly or execute code, placing it firmly in Write.

Attacks that exploit this kind of access
The rule that runs findAndReplaceTextInDocument 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 findAndReplaceTextInDocument, this is the rule to start with:
findAndReplaceTextInDocument 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Stable Baseline, apply this rule, and every findAndReplaceTextInDocument call is checked against it from then on.
Questions about findAndReplaceTextInDocument
Find and replace EXACT substrings in a document (NOT regex: wildcards and patterns are matched literally). Replaces EVERY occurrence and returns the replacement count; best for renames and repeated phrases. For a single targeted change at a known location, prefer editDocument (anchor patches). Case-sensitive by default. Diagrams/images are automatically protected — only document text is affected. Returns document.versionTimestamp (the fresh optimistic-lock token) like every other mutating tool, so you can chain straight into editDocument or the diagram tools. Pass versionTimestamp to opt into optimistic locking (optional here — whole-document find/replace is position-independent). Note: when the replace value contains a <!-- REFERENCE: {...} --> marker (e.g. inserting a user mention), it round-trips losslessly through the editor and triggers notifications if it adds a new user mention. 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.
findAndReplaceTextInDocument accepts 6 parameters: find, replace, documentId, caseSensitive, changeSummary, versionTimestamp. Required: find, replace, documentId. The full parameter table on this page comes from the server's own tool schema.
Register the Stable Baseline MCP server in PolicyLayer and add a rule for findAndReplaceTextInDocument: 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.
findAndReplaceTextInDocument 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 findAndReplaceTextInDocument 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 findAndReplaceTextInDocument. 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.
findAndReplaceTextInDocument is provided by the Stable Baseline MCP server (https://api.stablebaseline.io/functions/v1/cloud-serve/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
