Plane MCP Server

Instructions

Implementation Reference

• src/tools/module-issues.ts:14-27 (handler)

  The handler function that executes the tool: makes a GET request to the Plane API for module issues and returns the JSON response as text content.

  async ({ project_id, module_id }) => {
    const response = await makePlaneRequest(
      "GET",
      `workspaces/${process.env.PLANE_WORKSPACE_SLUG}/projects/${project_id}/modules/${module_id}/module-issues/`
    );
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify(response, null, 2),
        },
      ],
    };
  }

• src/tools/module-issues.ts:10-13 (schema)

  Input schema defined with Zod for project_id and module_id parameters.

  {
    project_id: z.string().describe("The uuid identifier of the project containing the module"),
    module_id: z.string().describe("The uuid identifier of the module to get issues for"),
  },

• src/tools/module-issues.ts:7-28 (registration)

  Registration of the list_module_issues tool on the MCP server, including schema and handler.

  server.tool(
    "list_module_issues",
    "Get all issues for a specific module",
    {
      project_id: z.string().describe("The uuid identifier of the project containing the module"),
      module_id: z.string().describe("The uuid identifier of the module to get issues for"),
    },
    async ({ project_id, module_id }) => {
      const response = await makePlaneRequest(
        "GET",
        `workspaces/${process.env.PLANE_WORKSPACE_SLUG}/projects/${project_id}/modules/${module_id}/module-issues/`
      );
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify(response, null, 2),
          },
        ],
      };
    }
  );

• src/tools/index.ts:19-19 (registration)

  Invocation of registerModuleIssueTools within the main registerTools function.

  registerModuleIssueTools(server);

• src/common/request-helper.ts:3-36 (helper)

  Helper function makePlaneRequest used by the handler to make authenticated HTTP requests to the Plane API.

  export async function makePlaneRequest<T>(method: string, path: string, body: any = null): Promise<T> {
    const hostUrl = process.env.PLANE_API_HOST_URL || "https://api.plane.so/";
    const host = hostUrl.endsWith("/") ? hostUrl : `${hostUrl}/`;
    const url = `${host}api/v1/${path}`;
    const headers: Record<string, string> = {
      "X-API-Key": process.env.PLANE_API_KEY || "",
    };
  
    // Only add Content-Type for non-GET requests
    if (method.toUpperCase() !== "GET") {
      headers["Content-Type"] = "application/json";
    }
  
    try {
      const config: AxiosRequestConfig = {
        url,
        method,
        headers,
      };
  
      // Only include body for non-GET requests
      if (method.toUpperCase() !== "GET" && body !== null) {
        config.data = body;
      }
  
      const response = await axios(config);
      return response.data;
    } catch (error) {
      if (axios.isAxiosError(error)) {
        throw new Error(`Request failed: ${error.message}`);
      }
      throw error;
    }
  }
