MCP Environment & Installation Manager

Implementation Reference

• src/tools/environment-tools.ts:146-174 (handler)

  Handler function that validates profileId and key inputs, ensures the profile exists, deletes the specified environment variable via configService.deleteEnvVar, and returns a JSON success response.

  async ({ profileId, key }, extra) => {
    if (!profileId.trim()) {
      throw new Error("Profile ID cannot be empty");
    }
    
    if (!key.trim()) {
      throw new Error("Environment variable key cannot be empty");
    }
    
    const profile = configService.getProfile(profileId);
    if (!profile) {
      throw new Error(`Profile not found: ${profileId}`);
    }
    
    configService.deleteEnvVar(profileId, key);
    
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify({
            success: true,
            profileId,
            key
          }, null, 2)
        }
      ]
    };
  }

• src/tools/environment-tools.ts:142-145 (schema)

  Zod schema for the tool inputs: profileId (string, required) and key (string, required).

  {
    profileId: z.string().describe("Profile ID to delete environment variable from"),
    key: z.string().describe("Environment variable key")
  },

• src/tools/environment-tools.ts:140-175 (registration)

  Registers the "delete-env-var" tool on the MCP server with its schema and handler function.

  server.tool(
    "delete-env-var",
    {
      profileId: z.string().describe("Profile ID to delete environment variable from"),
      key: z.string().describe("Environment variable key")
    },
    async ({ profileId, key }, extra) => {
      if (!profileId.trim()) {
        throw new Error("Profile ID cannot be empty");
      }
      
      if (!key.trim()) {
        throw new Error("Environment variable key cannot be empty");
      }
      
      const profile = configService.getProfile(profileId);
      if (!profile) {
        throw new Error(`Profile not found: ${profileId}`);
      }
      
      configService.deleteEnvVar(profileId, key);
      
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify({
              success: true,
              profileId,
              key
            }, null, 2)
          }
        ]
      };
    }
  );

• src/server.ts:31-31 (registration)

  High-level registration call that invokes registerEnvironmentTools, thereby registering the delete-env-var tool among others.

  registerEnvironmentTools(server, configService);
