WHAT IT DOES

What semantic_chunk does on ContextForge MCP Gateway

AI agents call semantic_chunk to retrieve information from ContextForge MCP Gateway without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why semantic_chunk is rated Low

Semantic chunking is a data analysis operation that processes input content to identify meaningful boundaries based on similarity metrics. It retrieves and analyzes data without modifying the source, creating new resources, executing arbitrary code, or destroying data. The output is derived information used for indexing or organization purposes.

From the tool's definition Tool name 'semantic_chunk' with description 'Semantic chunking based on content similarity' indicates analysis and partitioning of existing content. No creation, modification, deletion, or external execution is implied.

RECOMMENDED RULE

The rule that runs semantic_chunk safely

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

semantic_chunk Allowed

semantic_chunk is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "semantic_chunk": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect ContextForge MCP Gateway, apply this rule, and every semantic_chunk call is checked against it from then on.

How do I block semantic_chunk completely? +

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