Implementation Reference

  • The MCP tool handler for 'misp_toggle_feed' - accepts feedId (string) and enable (boolean), calls client.toggleFeed(), and returns a success or error message.
    // Enable/disable feed
    server.tool(
      "misp_toggle_feed",
      "Enable or disable a MISP feed",
      {
        feedId: z.string().describe("Feed ID"),
        enable: z.boolean().describe("true to enable, false to disable"),
      },
      async ({ feedId, enable }) => {
        try {
          await client.toggleFeed(feedId, enable);
          return {
            content: [
              {
                type: "text",
                text: `Feed ${feedId} ${enable ? "enabled" : "disabled"} successfully.`,
              },
            ],
          };
        } catch (err) {
          return {
            content: [
              {
                type: "text",
                text: `Error toggling feed: ${err instanceof Error ? err.message : String(err)}`,
              },
            ],
            isError: true,
          };
        }
      }
    );
  • Zod schema for the tool input: feedId (string) and enable (boolean).
    {
      feedId: z.string().describe("Feed ID"),
      enable: z.boolean().describe("true to enable, false to disable"),
    },
  • The client helper method that sends a POST request to /feeds/enable/<id> or /feeds/disable/<id> to toggle the feed status.
    async toggleFeed(
      feedId: string,
      enable: boolean
    ): Promise<{ message: string }> {
      return this.request<{ message: string }>(
        "POST",
        `/feeds/${enable ? "enable" : "disable"}/${encodeId(feedId, "feedId")}`
      );
    }
  • src/index.ts:40-40 (registration)
    Registration call in the main entry point that wires up the feed tools (including misp_toggle_feed) to the MCP server.
    registerFeedTools(server, client);
  • Helper function that validates and URL-encodes IDs to prevent path injection attacks.
    function encodeId(id: string, kind = "id"): string {
      if (!ID_PATTERN.test(id)) {
        throw new Error(`Invalid ${kind}: ${JSON.stringify(id)}`);
      }
      return encodeURIComponent(id);
    }
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, and the description lacks any behavioral details such as whether toggling requires specific permissions, affects data retrieval, or has irreversible consequences. The description carries the full burden but fails to disclose these traits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single front-loaded sentence with no waste. It is concise but could include a bit more context without losing brevity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple two-parameter toggle tool with no output schema, the description is minimally adequate. However, it lacks behavioral or usage context that would help an agent decide when to invoke it. Additional details would improve completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with clear parameter descriptions. The tool description adds no extra meaning beyond 'Feed ID' and 'true to enable, false to disable'. Baseline score of 3 is appropriate as the schema already does the work.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action 'Enable or disable a MISP feed', with a specific verb and resource. It distinguishes itself from sibling tools like misp_cache_feed and misp_fetch_feed which have different purposes.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to toggle a feed versus using other feed-related tools (e.g., cache, fetch). No mention of prerequisites or side effects, leaving the agent without context for appropriate use.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
