Part of the Knowledge Graph Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use publish_graph to create or modify resources in Knowledge Graph Server. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call publish_graph repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Knowledge Graph Server.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Publish a knowledge graph, changing its status from draft to published. Published graphs can still be modified, but it's recommended to track important changes through version management. Prerequisites: 1. Graph must exist and be in draft status 2. Recommended to ensure graph content is complete before publishing 3. Ensure all necessary nodes and edges have been added Usage recommendations: 1. First use list_graphs to check the current status of the graph 2. Use get_node_details to check the completeness of key nodes 3. Review the graph structure before publishing 4. Record publication time for version management 5. Notify relevant team members after publication Return data: - data: Published graph information * id: Graph ID * name: Graph name * type: Graph type * status: Published * publishedAt: Publication time. It is categorised as a Write tool in the Knowledge Graph Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for publish_graph. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Knowledge Graph Server MCP server.
publish_graph 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 publish_graph 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 publish_graph. 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.
publish_graph is provided by the Knowledge Graph Server MCP server (aiuluna/knowledge-graph-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
