Mervin Praison 6434a87b60 chore: remove completed AI SDK verification doc and bump version to 1.3.6
- Remove ai-sdk-backbone-verification.md (all tasks completed)
- Update package.json version from 1.3.5 to 1.3.6
- Refactor agent classes to use lazy-loaded AI SDK backend via resolveBackend()
- Convert direct createProvider() calls to async getProvider() pattern
- Add provider promise caching to prevent duplicate backend initialization
- Update ContextAgent, EnhancedAgent, ImageAgent, and PromptExpanderAgent classes
2025-12-30 17:15:40 +00:00
Mervin Praison 97d5b6db0d feat: add AI SDK backend support and embedding capabilities to Agent class
- Add AI SDK backend resolution with lazy initialization via getBackend()
- Add embed() method supporting single/batch text embeddings
- Add getBackendSource() to check backend type (ai-sdk/native/custom/legacy)
- Add getModel() to retrieve agent's model string
- Parse model string to extract provider/model ID for backend selection
- Use AI SDK backend for non-OpenAI providers (streaming and non-streaming)
- Export backend resolver an

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 519ad56e2b feat: add tokens_per_minute rate limiting and 429 error auto-retry
- Enhance RateLimiter class to support tokens_per_minute limiting
- Add acquire_tokens() method for token-based rate limiting
- Add wait_for_retry() methods for handling rate limit delays
- Add _call_with_retry() methods in LLM class for auto-retry on 429 errors
- Parse retry delay from API error responses (e.g., "retryDelay: 58s")
- Add rate_limiter, max_retries, retry_delay settings to LLM class

Closes #1086

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

# 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
