Mervin Praison 4996a9f9fa Merge remote-tracking branch 'origin/pr-1097-fixes' 2025-12-30 16:15:49 +00:00
Mervin Praison 54f4a96cba test: add comprehensive ImportError tests for MCP optional import
- Add test for MCP class ImportError when mcp package unavailable
- Add test for SSEMCPClient ImportError when mcp unavailable
- Add test for HTTPStreamMCPClient ImportError when mcp unavailable
- Add test for HTTPStreamMCPClient ImportError when aiohttp unavailable
- Fix unused import lint warnings (remove sys, add noqa for MCP)

These tests verify that actionable error messages with install instructions
are shown when users try to use MCP functionality without the mcp package.

Mervin Praison fff67a96de feat: improve rate limiting with retry wrappers and uncapped token wait times
- Add _completion_with_retry() and _acompletion_with_retry() convenience wrappers
- Remove max_retry_delay cap from internal token wait times to ensure correct rate limiting
- Add max_delay cap (300s default) to _parse_retry_delay() to prevent unbounded sleep from API errors
- Improve retry delay regex patterns (non-greedy matching, HTTP Retry-After header)
- Add documentation notes about large token requests exceeding burst capacity

majiayu000 98c5e8f175 fix: make MCP package import optional to prevent errors when not installed
Wrap mcp imports in try/except blocks in mcp.py, mcp_sse.py, and
mcp_http_stream.py. Add MCP_AVAILABLE flag to check availability at runtime.
When MCP class is instantiated without the mcp package installed, raise a
clear ImportError with installation instructions.

Closes #1091

# MCP Server Examples
Examples demonstrating the MCP Server v2 features per MCP Protocol Version 2025-11-25.
## Features Demonstrated
### 1. Pagination (`pagination_example.py`)
Demonstrates pagination for `tools/list`, `resources/list`, and `prompts/list`:
- Opaque cursor encoding (base64url)
- Server-determined page size (default: 50, max: 100)
- `nextCursor` for fetching more results
- Cursor validation with JSON-RPC errors
```bash
python pagination_example.py
```
### 2. Tool Annotations (`tool_annotations_example.py`)
Demonstrates MCP 2025-11-25 tool annotation hints:
- `readOnlyHint`: Tool only reads data
- `destructiveHint`: Tool may have destructive effects
- `idempotentHint`: Safe to call multiple times
- `openWorldHint`: Interacts with external world
```bash
python tool_annotations_example.py
```
### 3. CLI Tools (`cli_tools_example.sh`)
Demonstrates the new CLI commands:
```bash
# List tools with pagination
praisonai mcp list-tools --limit 10
praisonai mcp list-tools --cursor <cursor> --json
# Search tools
praisonai mcp tools search "query"
praisonai mcp tools search --category memory
praisonai mcp tools search --read-only
praisonai mcp tools search --json
# Get tool info
praisonai mcp tools info <tool-name>
praisonai mcp tools info <tool-name> --json
# Get tool schema
praisonai mcp tools schema <tool-name>
```
## API Reference
### Pagination
```python
from praisonai.mcp_server.registry import MCPToolRegistry
registry = MCPToolRegistry()
# ... register tools ...
# Get first page
tools, next_cursor = registry.list_paginated(page_size=50)
# Get next page
if next_cursor:
more_tools, next_cursor = registry.list_paginated(cursor=next_cursor)
```
### Tool Search
```python
# Search by query
tools, next_cursor, total = registry.search(query="memory")
# Filter by category
tools, _, _ = registry.search(category="file")
# Filter by read-only hint
tools, _, _ = registry.search(read_only=True)
# Combined filters with pagination
tools, next_cursor, total = registry.search(
query="data",
category="storage",
read_only=True,
page_size=10,
)
```
### Tool Annotations
```python
from praisonai.mcp_server.registry import MCPToolDefinition
# Read-only tool
tool = MCPToolDefinition(
name="data.read",
description="Read data",
handler=read_handler,
input_schema={"type": "object"},
read_only_hint=True,
destructive_hint=False,
)
# Destructive tool
tool = MCPToolDefinition(
name="file.delete",
description="Delete file",
handler=delete_handler,
input_schema={"type": "object"},
destructive_hint=True,
idempotent_hint=False,
)
```
## MCP Protocol Compliance
These examples comply with MCP Protocol Version 2025-11-25:
- Pagination uses opaque cursors (base64url encoded)
- Server determines page size (client cannot override)
- Invalid cursors return JSON-RPC error code -32602
- Tool annotations follow the spec defaults:
- `readOnlyHint`: false
- `destructiveHint`: true
- `idempotentHint`: false
- `openWorldHint`: true

# PraisonAI MCP Server Examples
This directory contains examples for running PraisonAI as an MCP (Model Context Protocol) server.
## Overview
PraisonAI can expose its capabilities via MCP protocol, allowing integration with:
- Claude Desktop
- Cursor
- Windsurf
- VSCode MCP clients
- Any MCP-compatible client
## Protocol Version
These examples use MCP Protocol Version **2025-11-25**.
## Examples
### 1. STDIO Server (stdio_server.py)
Run PraisonAI as an MCP server using STDIO transport (for Claude Desktop integration).
```bash
# Run directly
python stdio_server.py
# Or via CLI
praisonai mcp serve --transport stdio
```
### 2. HTTP Stream Server (http_stream_server.py)
Run PraisonAI as an MCP server using HTTP Stream transport.
```bash
# Run directly
python http_stream_server.py
# Or via CLI
praisonai mcp serve --transport http-stream --port 8080
```
### 3. Custom Tools Server (custom_tools_server.py)
Register custom tools and expose them via MCP.
```bash
python custom_tools_server.py
```
### 4. Client Example (mcp_client_example.py)
Example of connecting to a PraisonAI MCP server as a client.
```bash
python mcp_client_example.py
```
## CLI Commands
```bash
# Start STDIO server
praisonai mcp serve --transport stdio
# Start HTTP Stream server
praisonai mcp serve --transport http-stream --port 8080
# Start with authentication
praisonai mcp serve --transport http-stream --api-key YOUR_KEY
# List available tools
praisonai mcp list-tools
# List available resources
praisonai mcp list-resources
# List available prompts
praisonai mcp list-prompts
# Generate client configuration
praisonai mcp config-generate --client claude-desktop
# Check server health
praisonai mcp doctor
```
## Client Configuration

# Package Manager Example
This example demonstrates how to use the PraisonAI package manager for installing and managing Python packages with security defaults.
## Features Demonstrated
- Installing packages with version constraints
- Listing installed packages
- Searching for packages on PyPI
- Managing package index configuration
- Security features (dependency confusion prevention)
## Quick Start
```bash
# Run the example
python package_manager_example.py
```
## CLI Commands
### Install Packages
```bash
# Install a package
praisonai install requests
# Install with version constraint
praisonai install "requests>=2.28"
# Install multiple packages
praisonai install requests httpx aiohttp
# Upgrade existing package
praisonai install requests --upgrade
# JSON output
praisonai install requests --json
```
### Uninstall Packages
```bash
# Uninstall a package
praisonai uninstall requests
# Uninstall without confirmation
praisonai uninstall requests --yes
```
### List Packages
```bash
# List all installed packages
praisonai package list
# JSON output
praisonai package list --json
```
### Search Packages
```bash
# Search PyPI
praisonai package search langchain
# JSON output
praisonai package search langchain --json
```
### Index Configuration
```bash
# Show current index settings
praisonai package index show --json
# Set custom index
praisonai package index set https://pypi.mycompany.com/simple
# Reset to PyPI default
praisonai package index set https://pypi.org/simple
```
## Security Features
By default, only the primary index (PyPI) is used. Extra indexes are blocked to prevent dependency confusion attacks.
```bash
# This will FAIL (extra index not allowed by default)
praisonai install mypackage --extra-index-url https://other.index.com/simple
# Explicitly allow extra index (shows security warning)
praisonai install mypackage \
--extra-index-url https://other.index.com/simple \
--allow-extra-index
```
## Environment Variables
- `PRAISONAI_PACKAGE_INDEX_URL` - Override primary index URL
- `PIP_INDEX_URL` - Fallback to pip's index URL

Isolated Registry Example - Multi-Agent Safety
This example demonstrates how to use isolated registries to prevent
provider registration collisions in multi-agent scenarios.
Key concepts:
- Each agent/context can have its own registry
- No global state mutation
- Safe for concurrent/parallel runs
- Different agents can use different provider implementations
Requirements:

# Recipe Registry Example
This example demonstrates how to use the PraisonAI recipe registry for publishing and pulling recipes via both local filesystem and HTTP server.
## Features Demonstrated
- Creating a local registry
- Starting an HTTP registry server
- Publishing recipes with token authentication
- Listing and searching recipes
- Pulling recipes from HTTP registry
## Quick Start
```bash
# Run the HTTP registry example
python http_registry_example.py
```
## HTTP Registry Server
```bash
# Start HTTP registry server
praisonai registry serve --port 7777
# Start with authentication
praisonai registry serve --port 7777 --token mysecret
# Check server status
praisonai registry status --registry http://localhost:7777
```
## CLI Commands with HTTP Registry
```bash
# Publish to HTTP registry
praisonai recipe publish ./my-recipe --registry http://localhost:7777 --json
# Publish with token
praisonai recipe publish ./my-recipe --registry http://localhost:7777 --token mysecret
# Pull from HTTP registry
praisonai recipe pull [email protected] --registry http://localhost:7777 -o ./recipes
# List recipes from HTTP registry
praisonai recipe list --registry http://localhost:7777 --json
# Search HTTP registry
praisonai recipe search "hello" --registry http://localhost:7777
```
## Local Registry Commands
```bash
# Publish to local registry (default)
praisonai recipe publish ./my-recipe --json
# Pull from local registry
praisonai recipe pull [email protected] -o ./recipes
# Use custom local path
praisonai recipe publish ./my-recipe --registry /path/to/registry
```
## Environment Variables
- `PRAISONAI_REGISTRY_TOKEN` - Default token for HTTP registry authentication
## Default Registry Location
By default, the local registry is stored at `~/.praison/registry`.

# Security Features Example
This example demonstrates PraisonAI security features including SBOM generation, lockfile validation, dependency auditing, and PII redaction.
## Features Demonstrated
- **SBOM Generation**: Generate Software Bill of Materials in CycloneDX or SPDX format
- **Lockfile Validation**: Validate presence and format of dependency lockfiles
- **Dependency Auditing**: Audit dependencies for vulnerabilities
- **PII Redaction**: Detect and redact personally identifiable information
## Quick Start
```bash
python security_example.py
```
## CLI Commands
### SBOM Generation
```bash
# Generate CycloneDX SBOM
praisonai recipe sbom ./my-recipe --format cyclonedx -o sbom.json
# Generate SPDX SBOM
praisonai recipe sbom ./my-recipe --format spdx -o sbom.json
```
### Dependency Auditing
```bash
# Audit dependencies
praisonai recipe audit ./my-recipe
# Strict audit (fail on issues)
praisonai recipe audit ./my-recipe --strict
```
### Lockfile Validation
```bash
# Validate recipe (includes lockfile check)
praisonai recipe validate ./my-recipe --require-lockfile
```
## PII Redaction Configuration
In your `TEMPLATE.yaml`:
```yaml
data_policy:
pii:
mode: redact # allow, deny, or redact
fields:
- email
- phone
- ssn
- credit_card
```

# Production server with all features
praisonai recipe serve \
--host 0.0.0.0 \
--port 8765 \
--auth api-key \
--workers 4 \
--rate_limit 100 \
--enable_metrics \
--enable_admin
# Get metrics
curl http://localhost:8765/metrics
# Get OpenAPI spec
curl http://localhost:8765/openapi.json
# Hot reload recipes
curl -X POST http://localhost:8765/admin/reload \
-H "X-API-Key: your-key"
```
## CLI Commands
```bash
# Health check
praisonai endpoints health
# List recipes (with auth)
praisonai endpoints list --api-key your-key
# Invoke recipe
praisonai endpoints invoke my-recipe \
--input-json '{"query": "Hello"}' \
--api-key your-key \
--json
```
## Security Notes
- Always use `--auth api-key` when binding to `0.0.0.0`
- Store API keys in environment variables, not config files
- Use HTTPS in production (via reverse proxy)

Uses the token bucket algorithm:
- Tokens are added at a fixed rate (requests_per_minute / 60 per second)
- Each request consumes one token
- If no tokens available, wait until one is available
- Burst allows multiple requests in quick succession
Args:
requests_per_minute: Maximum requests per minute
tokens_per_minute: Optional token-based rate limiting (for future use)
burst: Maximum burst size (default: 1)
requests_per_minute: Maximum requests per minute (default: None)
tokens_per_minute: Maximum API tokens per minute for token-based limiting
burst: Maximum burst size (default: 1 for requests, auto-calculated for tokens)
max_retry_delay: Maximum delay in seconds for rate limit retries (default: 120)
Example:
# Request-based limiting
limiter = RateLimiter(requests_per_minute=60) # 1 req/sec
limiter.acquire() # Blocks if rate exceeded
# Token-based limiting (for API quotas like Gemini)
limiter = RateLimiter(tokens_per_minute=1000000) # 1M tokens/min
