Summary

This PR adds optional profiler data access capabilities to the Symfony bridge, enabling AI assistants to analyze Symfony profiler data for debugging and performance optimization through the Mate coding assistant.

Features

The Symfony bridge now provides two feature sets:

Container Introspection (always available):

Service listing and inspection
Container analysis

Profiler Data Access (optional, requires symfony/http-kernel and symfony/web-profiler-bundle):

Read and parse Symfony profiler files (gzipped, nested directory structure)
MCP tools for listing, searching, and retrieving profiler data (symfony-profiler-list, symfony-profiler-latest, symfony-profiler-search, symfony-profiler-get)
MCP resources for accessing specific profiles via symfony-profiler://profile/{token} URIs
Collector formatters for structured data presentation (request, exception)
Type-safe models with PHPStan types

Implementation Details

Namespace organization: Profiler classes under Symfony\AI\Mate\Bridge\Symfony\Profiler\*
Optional dependencies: Profiler dependencies in require-dev, tools only register when available
Conditional registration: Uses class_exists(\Symfony\Component\HttpKernel\Profiler\Profile::class) check
Follows Symfony patterns: Mirrors FrameworkBundle's conditional feature registration approach
Test coverage: 65 tests, 171 assertions, PHPStan clean (0 errors)

The README is too long, let's move it to the docs folder using rst

will not include them but i wanted to document the existing collectors - this should go into an issue after merging to track the state of the implementation

.phpstan/ForbidNativeExceptionRule.php

wachterjohannes · 2026-01-02T21:51:15Z

@chr-hertel @OskarStark i reduced the formatters to request and exception - so that the review is easier - we can add the other important collectors later

wachterjohannes · 2026-01-02T21:51:52Z

@chr-hertel @OskarStark @Nyholm its ready for review 🎉

> analyse the latest profile

∴ Thinking…

  The user wants me to analyze the latest profiler profile. Based on the project context, this is a Symfony application
  with the Symfony AI Mate MCP server available, which includes profiler-related tools.

  Looking at the available MCP tools, I can see:
  - profiler-latest - Get the latest profiler profile
  - profiler-get - Get a specific profile by token
  - profiler-list - List available profiler profiles
  - profiler-search - Search profiles by criteria

  The user wants to analyze the "latest profile", so I should use the profiler-latest tool to fetch it.

  According to the system reminder and MCP tool documentation, I should use these tools proactively. This is exactly the
  kind of task where I should leverage the Symfony AI Mate MCP server.

  Let me call the profiler-latest tool to get the most recent profiler profile.

⏺ I'll fetch and analyze the latest profiler profile for you.
  ⎿  {
         "token": "32d11b",
         "ip": "127.0.0.1",
         "method": "GET",
         "url": "https://127.0.0.1:8001/",
         "time": 1767386385,
         "time_formatted": "2026-01-02T20:39:45+00:00",
         "status_code": 200,
         "parent_token": null,
         "resource_uri": "profiler://profile/32d11b"
     }

∴ Thinking…

  The tool returned a summary of the latest profile. According to the documentation, this returns "summary data with resource_uri field - use the resource_uri to fetch full profile details including collectors".

  I need to use the ReadMcpResourceTool to fetch the full profile details using the resource_uri. The resource_uri is "profiler://profile/32d11b" and the server is "symfony-ai-mate".

⏺ Now let me fetch the full profile details including all collectors:

∴ Thinking…

  Good! I now have the full profile with all available collectors. This is a GET request to the homepage (https://127.0.0.1:8001/) with a 200 status code. I can see there are 19 collectors available, including some interesting ones:

  - Standard Symfony collectors: request, time, memory, exception, logger, events, router, cache, twig
  - Twig LiveComponent collector
  - AI-specific collectors: Symfony\AI\AiBundle\Profiler\DataCollector and Symfony\AI\McpBundle\Profiler\DataCollector

  Let me fetch the most important collectors to provide a comprehensive analysis. I should focus on:
  1. Time (performance)
  2. Memory (resource usage)
  3. Request (basic info)
  4. Exception (any errors)
  5. Logger (any logged messages)
  6. AI Bundle collector (AI-specific data)
  7. MCP Bundle collector (MCP-specific data)

  Let me fetch these key collectors in parallel.

     }

∴ Thinking…

  I've collected the key collectors. Let me analyze what I have:

  1. Time collector: Empty raw data - this suggests the time data collection might not be working properly or the data format is different
  2. Memory collector: Empty raw data - similar issue
  3. Request collector: Good data! This shows:
    - GET request to "/"
    - Route: "index"
    - Controller: array (count=4)
    - 200 OK response
    - Content-Type: text/html; charset=UTF-8
    - Session is stateless
    - Environment variables: APP_ENV, APP_SECRET, HUGGINGFACE_API_KEY, OPENAI_API_KEY
  4. Exception collector: No exceptions (good!)
  5. Logger collector: Empty raw data
  6. AI Bundle collector: Empty raw data - no AI activity
  7. MCP Bundle collector: Empty raw data - no MCP activity
  8. Router collector: Empty raw data

  The collectors with "raw: {}" seem to indicate no data was collected for those collectors. This might be normal for a simple homepage request where no AI/MCP operations occurred, no logging happened, etc.

  Let me try to fetch the twig_component collector since this is a LiveComponent application, that might have interesting data:

⏺ Let me also check the Twig component collector since this is a LiveComponent application:

⏺ readMcpResource(Read resource "profiler://profile/32d11b/twig_component" from server "symfony-ai-mate")
  ⎿  {
       "contents": [
         {
           "uri": "profiler://profile/32d11b/twig_component",

           "text": "{\n    \"name\": \"twig_component\",\n    \"data\": {\n        \"raw\": {}\n    },\n    \"summary\": []\n}"
         }
       ]
     }

∴ Thinking…

  Alright, I have enough data to provide a comprehensive analysis. Let me summarize what I found:

  The profile is for a simple GET request to the homepage ("/") that returned a 200 OK response. Most collectors show no activity because this was likely just a page load without any AI operations, logging, exceptions, or complex processing.

  Let me provide a clear, structured analysis for the user.

⏺ Profile Analysis - Token: 32d11b

  Request Overview

  - URL: https://127.0.0.1:8001/
  - Method: GET
  - Route: index
  - Status: 200 OK
  - Time: 2026-01-02 20:39:45 UTC
  - IP: 127.0.0.1

  Key Findings

  ✅ Request Details (demo/CLAUDE.md:1)
  - Path: / (homepage)
  - Controller: Array-based controller
  - Content-Type: text/html; charset=UTF-8
  - Format: HTML
  - Locale: en

  ✅ No Errors (demo/CLAUDE.md:1)
  - Exception collector reports: has_exception: false
  - Clean request with no errors or warnings

  ✅ Session State (demo/CLAUDE.md:1)
  - Session is stateless
  - No flash messages
  - No session attributes or metadata
  - Cookie: admin_deauth_profile_token (redacted)

  ✅ Environment Configuration (demo/CLAUDE.md:1)
  - APP_ENV configured
  - APP_SECRET configured
  - HUGGINGFACE_API_KEY configured
  - OPENAI_API_KEY configured

  Inactive Collectors

  The following collectors show no activity (empty raw data):
  - Time: No timing data captured
  - Memory: No memory metrics captured
  - Logger: No log messages during this request
  - AI Bundle: No AI operations performed
  - MCP Bundle: No MCP tool calls made
  - Twig Component: No LiveComponent interactions
  - Router: No additional routing data

  Analysis Summary

  This appears to be a simple homepage load without any:
  - AI agent interactions
  - MCP tool usage
  - LiveComponent rendering
  - Database queries
  - Logging activity
  - Exceptions or errors

  The request executed cleanly and returned the index template successfully. The empty collectors suggest this was likely the initial page load before any user interaction with the chat interfaces or AI features.

  Recommendation: To see more interesting profiler data, trigger a request that involves AI chat, streaming, or MCP tool usage (e.g., /blog, /stream, /youtube routes).

I dont like the empty returns for none registered formatters - but for the first implementation i think its ok - also this should to into an issue.

Nyholm · 2026-01-03T07:50:54Z

This looks nice, but can we merge this with the SymfonyBridge?

wachterjohannes · 2026-01-03T13:22:30Z

@Nyholm also considered this, but the profiler makes more sense as its own extension. This way, it can be enabled and configured independently, adding context to the prompt without coupling it to other extensions.

Open Points are:

Other Collectors (Link to comment) - will go to an own issue after merge
Empty Data for none fomatted collectors (Link to comment) - will go to an own issue after merge
Decission: Merge Profiler Extension with Symfony Extension (Link to comment) - needs a decission before merge
Throwables (Link to comment) - @chr-hertel are the catches OK? discussed with @chr-hertel in slack and its ok in that case
Using FileProfilerStorage instead of Reimplementing it (Link to comment)

@sonnymilton thanks for the feedback - i have done that now

This bridge provides MCP (Model Context Protocol) integration with the Symfony Profiler, allowing AI assistants to analyze profiler data for debugging and performance optimization. Key features: - Read and parse Symfony profiler files (gzipped, nested directory structure) - MCP tools for listing, searching, and retrieving profiler data - MCP resources for accessing specific profile sections (request, response, events, exceptions) - Collector formatters for structured data presentation (request, response, event, exception) - Type-safe models with PHPStan types (ProfileIndexData, CollectorDataArray) - Comprehensive test coverage (69 tests, 174 assertions) The bridge enables AI-powered analysis of web application performance, request handling, and error debugging through the Mate coding assistant.

…ofileData Major changes: - Simplify ProfileData to wrap Symfony Profile + context (for multi-directory support) - Update ProfilerDataProvider to use FileProfilerStorage instead of manual file operations - Update ProfilerResourceTemplate to access data through Profile methods - Add FileProfilerStorage and Profile imports to config.php - Update ProfileDataTest to test simplified model - Update ProfilerDataProviderTest for new ProfileData structure Benefits: - Use official Symfony API (FileProfilerStorage) instead of manual file operations - Future-proof against Symfony profiler format changes - Cleaner code with less maintenance burden - Preserve multi-context support through ProfileData wrapper Note: Some tests still need fixture updates to work with FileProfilerStorage format

- Update test expectations for newest-first sorting order - Create TestCollector fixture class with proper serialization support - Regenerate test fixtures using FileProfilerStorage API - Update ProfilerTool to work with new ProfileData structure - Remove unused ProfileIndexer dependency - Fix all PHPStan type errors - All 64 tests passing, 0 PHPStan errors Removes ProfileIndexer from service dependency chain as it's no longer needed with FileProfilerStorage handling all file operations.

Implements comprehensive data sanitization to prevent exposure of sensitive information through the profiler MCP tool: Security Measures: - Redact all cookie values (session tokens, CSRF tokens, etc.) - Redact sensitive HTTP headers (Authorization, Cookie, X-API-Key, etc.) - Redact environment variables containing sensitive patterns: SECRET, KEY, PASSWORD, TOKEN, BEARER, AUTH, CREDENTIAL, PRIVATE - Redact all session attributes - Preserve non-sensitive data for debugging purposes Pattern Matching: - Case-insensitive header matching - Case-insensitive environment variable pattern matching - Comprehensive test coverage (7 new tests, 42 assertions) Prevents exposure of: - Session cookies (admin_deauth_profile_token, etc.) - API keys (OPENAI_API_KEY, HUGGINGFACE_API_KEY, etc.) - Application secrets (APP_SECRET, JWT_TOKEN, etc.) - Database credentials (DATABASE_PASSWORD, etc.) - Authorization headers and tokens All 71 tests passing, 0 PHPStan errors

Profiler Bridge Dependencies: - Add symfony/http-kernel and symfony/var-dumper to mate require-dev (needed for testing embedded Profiler Bridge) - Add symfony/var-dumper to Profiler Bridge require-dev (for standalone installation) - Bridge dependencies are defined in Bridge composer.json but loaded via mate's vendor when embedded PHPStan Configuration: - Add excludePaths for src/Bridge/*/vendor to prevent scanning bridge vendor directories if accidentally created Code Quality: - Remove deprecated setAccessible() calls (not needed in PHP 8.1+) - Remove unused ProfileIndexer imports from test files - Remove unused FileProfilerStorage/Profile imports from config - Reorganize RequestCollectorFormatter methods for better readability All 71 tests passing, 0 PHPStan errors

wachterjohannes · 2026-01-11T19:51:51Z

@chr-hertel @Nyholm i merged the tools into the symfony bridge - you can review it BUT before merging i have to take a deeper test in the demo application - was not able todo this today

The Profiler bridge has been merged into the Symfony bridge to consolidate all Symfony-related tooling in one package. This reduces maintenance overhead and simplifies the extension architecture. Key changes: - All profiler classes moved to Symfony\AI\Mate\Bridge\Symfony\Profiler namespace - Tool names updated with symfony- prefix (symfony-profiler-list, etc.) - Resource URIs updated to use symfony-profiler:// scheme - Profiler dependencies moved to require-dev (optional feature) - Conditional service registration using class_exists() check - Container introspection works independently of profiler - Test fixtures regenerated with correct namespace - All tests passing (65 tests, 171 assertions) - PHPStan analysis clean (0 errors)

wachterjohannes · 2026-01-12T18:24:08Z

@chr-hertel @Nyholm tested and OK for the first release :) see it here https://asciinema.org/a/paNQKKiSIQyOolsx

src/mate/src/Bridge/Symfony/Profiler/Service/Formatter/ExceptionCollectorFormatter.php

Updated ExceptionCollectorFormatter and RequestCollectorFormatter to use specific collector types (ExceptionDataCollector and RequestDataCollector) instead of the generic DataCollectorInterface. Benefits: - Better static analysis with PHPStan understanding exact types - Removed defensive method_exists() checks (65 lines removed) - Type assertions provide runtime safety - Cleaner, more maintainable code - Direct access to collector-specific methods The generic template annotation tells PHPStan about the specific type, while runtime assertions ensure type safety.
