René's URL Explorer Experiment

{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Resource template parameters do not support values with slashes","articleBody":"**Describe the bug**\n\n## Overview\nResource template values containing path separators (slashes) do not work.\n\n## Working Examples\n\n### Simple Static Resources\n```python\n@mcp.resource(\"resource://my-resource\")\ndef get_data() -\u003e dict[str, Any]:\n    return {\n        \"contents\": [{\n            \"uri\": \"resource://my-resource\",\n            \"mimeType\": \"text/plain\",\n            \"text\": \"Hello, world!\"\n        }]\n    }\n```\nThis works reliably and shows up in the Inspector UI.\n\n### Parameter \n```python\n@mcp.resource(\"resource://{value}\")\ndef get_content(value: str) -\u003e dict[str, Any]:\n    # This works for: resource://\n    # But fails for: resourse://value/with/slashes\n    ...\n```\n\n**To Reproduce**\n\n### 1. Template Pattern with Regex\n```python\n@mcp.resource(\"resource://{value:.*}\")\ndef get_content(value: str) -\u003e dict[str, Any]:\n    # Error: Mismatch between URI parameters set() and function parameters {'permalink'}\n```\n\n### 2. Generic Catch-all Pattern\n```python\n@mcp.resource(\"memory://*\")\ndef get_content(uri: str) -\u003e dict[str, Any]:\n    # Error: Mismatch between URI parameters set() and function parameters {'uri'}\n```\n\n### 3. Path Parameter Approach\n```python\n@mcp.resource(\"resource://content/{path}\")\ndef get_content(path: str) -\u003e dict[str, Any]:\n    # Works for simple paths but fails with slashes in {path}\n```\n\n### 4. Base Path with Query Parameters\n```python\n@mcp.resource(\"resource://content\")\ndef get_content(path: str = None) -\u003e dict[str, Any]:\n    # Error: Mismatch between URI parameters set() and function parameters {'path'}\n```\n\n**Expected behavior**\n\nResource Templates with slashes in the value should be passed to the decorated function. \n\n","author":{"url":"https://github.com/phernandez","@type":"Person","name":"phernandez"},"datePublished":"2025-01-20T17:15:52.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/159/python-sdk/issues/159"}
