Implementation Reference

src/tools/settings-tools.ts:236-248 (handler)

Handler function that parses the input value as JSON and sends a PUT request to the Meilisearch API endpoint for updating filterable attributes (`/indexes/{indexUid}/settings/filterable-attributes`). Returns the response or error.

async ({ indexUid, value }) => {
  try {
    // Parse the value string to ensure it's valid JSON
    const parsedValue = JSON.parse(value);
    
    const response = await apiClient.put(`/indexes/${indexUid}/settings/${endpoint}`, parsedValue);
    return {
      content: [{ type: "text", text: JSON.stringify(response.data, null, 2) }],
    };
  } catch (error) {
    return createErrorResponse(error);
  }
}

src/tools/settings-tools.ts:232-235 (schema)
Input schema using Zod: requires indexUid (string) and value (string representing JSON for the setting).
```
{
  indexUid: z.string().describe("Unique identifier of the index"),
  value: z.string().describe("JSON value for the setting"),
},
```
src/tools/settings-tools.ts:180-184 (registration)
Configuration object in updateSettingsTools array that defines the tool name, endpoint, and description for dynamic registration.
```
{
  name: "update-filterable-attributes",
  endpoint: "filterable-attributes",
  description: "Update the filterable attributes setting",
},
```

src/tools/settings-tools.ts:228-249 (registration)

Dynamic registration loop that creates the server.tool call for 'update-filterable-attributes' using the config, schema, and handler.

updateSettingsTools.forEach(({ name, endpoint, description }) => {
  server.tool(
    name,
    description,
    {
      indexUid: z.string().describe("Unique identifier of the index"),
      value: z.string().describe("JSON value for the setting"),
    },
    async ({ indexUid, value }) => {
      try {
        // Parse the value string to ensure it's valid JSON
        const parsedValue = JSON.parse(value);
        
        const response = await apiClient.put(`/indexes/${indexUid}/settings/${endpoint}`, parsedValue);
        return {
          content: [{ type: "text", text: JSON.stringify(response.data, null, 2) }],
        };
      } catch (error) {
        return createErrorResponse(error);
      }
    }
  );

src/index.ts:67-67 (registration)
Top-level call to registerSettingsTools(server), which registers all settings tools including 'update-filterable-attributes'.
```
registerSettingsTools(server);
```
