πŸ” Tool Discovery Summary πŸ“Š Total: 19 tools from 4/4 servers

βœ… Weather Server (weatherServer) πŸ“Š 2 tools available

πŸ”§ weatherServer.getAlerts Get weather alerts for a state. Returns JSON with features array containing alert objects. Each alert has properties: { event, severity, areaDesc, headline, description, instruction, effective, expires, ends }. Severity levels: Extreme, Severe, Moderate, Minor. πŸ”§ weatherServer.getForecast Get weather forecast for a location. Returns JSON with properties.periods array containing forecast objects with name, temperature, temperatureUnit, windSpeed, windDirection, shortForecast, detailedForecast.

βœ… Geocode Server (geocodeServer) πŸ“Š 1 tools available

πŸ”§ geocodeServer.geocode Convert a location name to latitude/longitude coordinates. Returns structured data with latitude, longitude, and formatted address information.

βœ… File System Server (filesystemServer) πŸ“Š 14 tools available

πŸ”§ filesystemServer.readFile Read the complete contents of a file as text. DEPRECATED: Use filesystemServer.readTextFile instead. πŸ”§ filesystemServer.readTextFile Read the complete contents of a file from the file system as text. Handles various text encodings and provides detailed error messages if the file cannot be read. Use this tool when you need to examine the contents of a single file. Use the 'head' parameter to read only the first N lines of a file, or the 'tail' parameter to read only the last N lines of a file. Operates on the file as text regardless of extension. Only works within allowed directories. πŸ”§ filesystemServer.readMediaFile Read an image or audio file. Returns the base64 encoded data and MIME type. Only works within allowed directories. πŸ”§ filesystemServer.readMultipleFiles Read the contents of multiple files simultaneously. This is more efficient than reading files one by one when you need to analyze or compare multiple files. Each file's content is returned with its path as a reference. Failed reads for individual files won't stop the entire operation. Only works within allowed directories. πŸ”§ filesystemServer.writeFile Create a new file or completely overwrite an existing file with new content. Use with caution as it will overwrite existing files without warning. Handles text content with proper encoding. Only works within allowed directories. πŸ”§ filesystemServer.editFile Make line-based edits to a text file. Each edit replaces exact line sequences with new content. Returns a git-style diff showing the changes made. Only works within allowed directories. πŸ”§ filesystemServer.createDirectory Create a new directory or ensure a directory exists. Can create multiple nested directories in one operation. If the directory already exists, this operation will succeed silently. Perfect for setting up directory structures for projects or ensuring required paths exist. Only works within allowed directories. πŸ”§ filesystemServer.listDirectory Get a detailed listing of all files and directories in a specified path. Results clearly distinguish between files and directories with [FILE] and [DIR] prefixes. This tool is essential for understanding directory structure and finding specific files within a directory. Only works within allowed directories. πŸ”§ filesystemServer.listDirectoryWithSizes Get a detailed listing of all files and directories in a specified path, including sizes. Results clearly distinguish between files and directories with [FILE] and [DIR] prefixes. This tool is useful for understanding directory structure and finding specific files within a directory. Only works within allowed directories. πŸ”§ filesystemServer.directoryTree Get a recursive tree view of files and directories as a JSON structure. Each entry includes 'name', 'type' (file/directory), and 'children' for directories. Files have no children array, while directories always have a children array (which may be empty). The output is formatted with 2-space indentation for readability. Only works within allowed directories. πŸ”§ filesystemServer.moveFile Move or rename files and directories. Can move files between directories and rename them in a single operation. If the destination exists, the operation will fail. Works across different directories and can be used for simple renaming within the same directory. Both source and destination must be within allowed directories. πŸ”§ filesystemServer.searchFiles Recursively search for files and directories matching a pattern. Searches through all subdirectories from the starting path. The search is case-insensitive and matches partial names. Returns full paths to all matching items. Great for finding files when you don't know their exact location. Only searches within allowed directories. πŸ”§ filesystemServer.getFileInfo Retrieve detailed metadata about a file or directory. Returns comprehensive information including size, creation time, last modified time, permissions, and type. This tool is perfect for understanding file characteristics without reading the actual content. Only works within allowed directories. πŸ”§ filesystemServer.listAllowedDirectories Returns the list of directories that this server is allowed to access. Subdirectories within these allowed directories are also accessible. Use this to understand which directories and their nested paths are available before trying to access files.

βœ… Brave Search (braveSearch) πŸ“Š 2 tools available

πŸ”§ braveSearch.braveWebSearch Performs a web search using the Brave Search API, ideal for general queries, news, articles, and online content. Use this for broad information gathering, recent events, or when you need diverse web sources. Supports pagination, content filtering, and freshness controls. Maximum 20 results per request, with offset for pagination. πŸ”§ braveSearch.braveLocalSearch Searches for local businesses and places using Brave's Local Search API. Best for queries related to physical locations, businesses, restaurants, services, etc. Returns detailed information including:

  • Business names and addresses
  • Ratings and review counts
  • Phone numbers and opening hours Use this when the query implies 'near me' or mentions specific locations. Automatically falls back to web search if no local results are found.

Tool Mapping (use these scoped names in your code): πŸ”§ filesystemServer.directoryTree() [from File System Server] ⚠️ NO OUTPUT SCHEMA OR AUGMENTATION - May need exploration πŸ”§ filesystemServer.getFileInfo() [from File System Server] ⚠️ NO OUTPUT SCHEMA OR AUGMENTATION - May need exploration

<augmentation_workflow> ⚠️ IMPORTANT: If tool output is unclear, CREATE AN AUGMENTATION!

DO NOT trial-and-error different parsing approaches. Follow this workflow:

  1. Call execute-code with // EXPLORING comment to inspect raw output
  2. When output is unclear/hard to parse, STOP and create augmentation
  3. Call add-augmentation with proper markdown documentation
  4. Call get-tool-apis again to see enhanced JSDoc
  5. THEN write parsing code with full understanding

This is MANDATORY when struggling with output. See execute-code for template. </augmentation_workflow>

πŸ”§ weatherServer.getAlerts Get weather alerts for a state. Returns JSON with features array containing alert objects. Each alert has properties: { event, severity, areaDesc, headline, description, instruction, effective, expires, ends }. Severity levels: Extreme, Severe, Moderate, Minor. πŸ”§ weatherServer.getForecast Get weather forecast for a location. Returns JSON with properties.periods array containing forecast objects with name, temperature, temperatureUnit, windSpeed, windDirection, shortForecast, detailedForecast.

βœ… Geocode Server (geocodeServer) πŸ“Š 1 tools available

πŸ”§ geocodeServer.geocode Convert a location name to latitude/longitude coordinates. Returns structured data with latitude, longitude, and formatted address information.

βœ… File System Server (filesystemServer) πŸ“Š 14 tools available

πŸ”§ filesystemServer.readFile Read the complete contents of a file as text. DEPRECATED: Use filesystemServer.readTextFile instead. πŸ”§ filesystemServer.readTextFile Read the complete contents of a file from the file system as text. Handles various text encodings and provides detailed error messages if the file cannot be read. Use this tool when you need to examine the contents of a single file. Use the 'head' parameter to read only the first N lines of a file, or the 'tail' parameter to read only the last N lines of a file. Operates on the file as text regardless of extension. Only works within allowed directories. πŸ”§ filesystemServer.readMediaFile Read an image or audio file. Returns the base64 encoded data and MIME type. Only works within allowed directories. πŸ”§ filesystemServer.readMultipleFiles Read the contents of multiple files simultaneously. This is more efficient than reading files one by one when you need to analyze or compare multiple files. Each file's content is returned with its path as a reference. Failed reads for individual files won't stop the entire operation. Only works within allowed directories. πŸ”§ filesystemServer.writeFile Create a new file or completely overwrite an existing file with new content. Use with caution as it will overwrite existing files without warning. Handles text content with proper encoding. Only works within allowed directories. πŸ”§ filesystemServer.editFile Make line-based edits to a text file. Each edit replaces exact line sequences with new content. Returns a git-style diff showing the changes made. Only works within allowed directories. πŸ”§ filesystemServer.createDirectory Create a new directory or ensure a directory exists. Can create multiple nested directories in one operation. If the directory already exists, this operation will succeed silently. Perfect for setting up directory structures for projects or ensuring required paths exist. Only works within allowed directories. πŸ”§ filesystemServer.listDirectory Get a detailed listing of all files and directories in a specified path. Results clearly distinguish between files and directories with [FILE] and [DIR] prefixes. This tool is essential for understanding directory structure and finding specific files within a directory. Only works within allowed directories. πŸ”§ filesystemServer.listDirectoryWithSizes Get a detailed listing of all files and directories in a specified path, including sizes. Results clearly distinguish between files and directories with [FILE] and [DIR] prefixes. This tool is useful for understanding directory structure and finding specific files within a directory. Only works within allowed directories. πŸ”§ filesystemServer.directoryTree Get a recursive tree view of files and directories as a JSON structure. Each entry includes 'name', 'type' (file/directory), and 'children' for directories. Files have no children array, while directories always have a children array (which may be empty). The output is formatted with 2-space indentation for readability. Only works within allowed directories. πŸ”§ filesystemServer.moveFile Move or rename files and directories. Can move files between directories and rename them in a single operation. If the destination exists, the operation will fail. Works across different directories and can be used for simple renaming within the same directory. Both source and destination must be within allowed directories. πŸ”§ filesystemServer.searchFiles Recursively search for files and directories matching a pattern. Searches through all subdirectories from the starting path. The search is case-insensitive and matches partial names. Returns full paths to all matching items. Great for finding files when you don't know their exact location. Only searches within allowed directories. πŸ”§ filesystemServer.getFileInfo Retrieve detailed metadata about a file or directory. Returns comprehensive information including size, creation time, last modified time, permissions, and type. This tool is perfect for understanding file characteristics without reading the actual content. Only works within allowed directories. πŸ”§ filesystemServer.listAllowedDirectories Returns the list of directories that this server is allowed to access. Subdirectories within these allowed directories are also accessible. Use this to understand which directories and their nested paths are available before trying to access files.

βœ… Brave Search (braveSearch) πŸ“Š 2 tools available

πŸ”§ braveSearch.braveWebSearch Performs a web search using the Brave Search API, ideal for general queries, news, articles, and online content. Use this for broad information gathering, recent events, or when you need diverse web sources. Supports pagination, content filtering, and freshness controls. Maximum 20 results per request, with offset for pagination. πŸ”§ braveSearch.braveLocalSearch Searches for local businesses and places using Brave's Local Search API. Best for queries related to physical locations, businesses, restaurants, services, etc. Returns detailed information including:

  • Business names and addresses
  • Ratings and review counts
  • Phone numbers and opening hours Use this when the query implies 'near me' or mentions specific locations. Automatically falls back to web search if no local results are found.

  /**
   * Retrieve detailed metadata about a file or directory. Returns comprehensive information including size, creation time, last modified time, permissions, and type. This tool is perfect for understanding file characteristics without reading the actual content. Only works within allowed directories.
   *
   * ## Output Format
   * Returns a ToolResult with content array containing a text field. The text is a formatted string with key-value pairs separated by newlines.
   *
   * ### Fields
   * - **size**: number - File size in bytes (no commas, lowercase "size:")
   * - **created**: string - Creation timestamp
   * - **modified**: string - Last modification timestamp
   * - **accessed**: string - Last access timestamp
   * - **isDirectory**: boolean - Whether path is a directory
   * - **isFile**: boolean - Whether path is a file
   * - **permissions**: string - Unix file permissions (e.g., "644")
   *
   * ### Example Output
   * ```
   * size: 77
   * created: Wed Oct 01 2025 16:07:40 GMT-0400 (Eastern Daylight Time)
   * modified: Wed Oct 01 2025 16:07:40 GMT-0400 (Eastern Daylight Time)
   * accessed: Wed Oct 01 2025 16:07:41 GMT-0400 (Eastern Daylight Time)
   * isDirectory: false
   * isFile: true
   * permissions: 644
   * ```
   *
   * ### Parsing Example
   * ```typescript
   * const fileInfo = await filesystemServer.getFileInfo({ path: '/some/file.txt' });
   * const infoText = fileInfo.content[0].text;
   *
   * // Parse size (lowercase "size:", no commas)
   * const sizeMatch = infoText.match(/^size: (\d+)/m);
   * const size = sizeMatch ? parseInt(sizeMatch[1]) : 0;
   *
   * // Parse other fields
   * const isDirectory = /^isDirectory: true/m.test(infoText);
   * const isFile = /^isFile: true/m.test(infoText);
   * const permissionsMatch = infoText.match(/^permissions: (.+)/m);
   * const permissions = permissionsMatch ? permissionsMatch[1] : '';

Tool Mapping (use these scoped names in your code): πŸ”§ filesystemServer.directoryTree() [from File System Server] βœ… Has augmentation πŸ”§ filesystemServer.getFileInfo() [from File System Server] βœ… Has augmentation

<augmentation_workflow> ⚠️ IMPORTANT: If tool output is unclear, CREATE AN AUGMENTATION!

DO NOT trial-and-error different parsing approaches. Follow this workflow:

  1. Call execute-code with // EXPLORING comment to inspect raw output
  2. When output is unclear/hard to parse, STOP and create augmentation
  3. Call add-augmentation with proper markdown documentation
  4. Call get-tool-apis again to see enhanced JSDoc
  5. THEN write parsing code with full understanding

This is MANDATORY when struggling with output. See execute-code for template. </augmentation_workflow>
