Canary (#1166)
* feat(python): add E2E testing for Python server in CI workflow - Introduced a new job in the GitHub Actions workflow to run end-to-end tests against the Python MCP server. - Updated the inspector.py to allow overriding the CDN base URL via an environment variable. - Added a new script command for running Python E2E tests in the package.json. - Enhanced documentation to include instructions for running Python server E2E tests. * fix(inspector): skip proxy when inspector is served from the MCP server itself When the inspector is embedded in a Python (or other) MCP server, the window.location.origin matches the MCP server's origin, so /inspector/api/proxy doesn't exist there. Routing auto-connect through that missing proxy caused silent connection failures. Now proxyAddress is only set when the inspector origin differs from the target URL's origin (i.e. the inspector has its own server running). Also add echo tool to server_example.py so python.test.ts can pass. * fix(inspector): detect proxy availability via runtime config injection Inject window.__MCP_PROXY_URL__ from the inspector server when it serves the HTML. When served from a Python/custom MCP server (same origin), the flag is absent and autoProxyFallback is disabled so no proxy is used. - Add proxyUrl to RuntimeConfig in shared-static.ts - Default to /inspector/api/proxy when inspector server serves - Read __MCP_PROXY_URL__ in App.tsx and configure defaultAutoProxyFallback - Disable autoProxyFallback when no proxy is available (no hosted fallback) * ci: trigger inspector E2E workflow on PRs to canary/main * ci: temporarily disable mix/prod/builtin E2E jobs for Python testing * ci: re-enable all E2E jobs, workflow_dispatch only * ci: re-enable E2E jobs for Python testing in CI workflow * chore: enter canary prerelease mode * chore(typescript): version packages (canary) * fix(inspector): resolve auto-connect issues for embedded servers This patch release addresses the auto-connect functionality of the inspector when served from an MCP server. Key changes include skipping the proxy when the inspector's origin matches the MCP server's origin and detecting proxy availability through runtime configuration. Additionally, the mcp-use package has been updated to version 1.21.2. --------- Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> |

feat(python): add icons parameter to MCPServer constructor (#1147)
* fix(python/server): simplify tool JSON Schema for Optional parameters
Pydantic generates {"anyOf": [{"type": "T"}, {"type": "null"}]} for
Optional[T] tool parameters. While valid JSON Schema 2020-12, this
pattern breaks description rendering in the MCP Inspector UI and fails
Gemini API validation (requires top-level type field). MCP signals
optionality via the required array, making the anyOf/null wrapper
redundant.
- Add simplify_optional_schema() utility that collapses nullable anyOf
into flat {"type": "T"} while preserving description, default, title
- Override MCPServer.add_tool() to apply simplification after Pydantic
generates the schema
- Add 12 unit tests for the schema simplifier (test_json_schema.py)
- Add 23 unit tests for tool schema output (test_list_tool_format.py)
- Update server_example.py with representative parameter patterns
including Literal enum types
* docs(python/server): add parameter types and JSON Schema section to tools docs
Document the Python-to-JSON-Schema type mapping, required/optional/nullable
parameter patterns, and Literal enum usage. Includes a note explaining the
anyOf/null simplification that mcp-use applies automatically.
* feat(python/server): add icons parameter to MCPServer constructor
Pass through the icons parameter to FastMCP so server-level icons can
be set directly in the MCPServer constructor.
* docs(python/server): document icons parameter in server overview
* docs(python): update server example with icons and Literal enum params
* style: format server_example.py
* test(python): add unit tests for icons constructor parameter
* docs: regenerate API reference for icons param

fix(python/server): improve debug and pretty_print_jsonrpc behavior (#814)
* fix(python/server): improve debug and pretty_print_jsonrpc behavior - Make pretty_print_jsonrpc work independently of debug_level (previously required DEBUG=2 environment variable) - Rename run_debug to debug in server.run() for consistency - Make run(debug=True) override server's debug_level if it was 0 - Remove aggressive signal handlers that broke thread compatibility (uvicorn handles SIGINT/SIGTERM gracefully) - Update all documentation to use new debug parameter name * refactor(python/server): remove unused lupo_tool function from server_example.py * docs: update signals API reference after simplification * refactor: remove unused signals.py module uvicorn already handles SIGINT/SIGTERM gracefully, so custom signal handlers are unnecessary. Removed the signals.py file and all references to setup_signal_handlers(). * chore: remove analysis files |

feat(python): introduce roots support in MCPClient and Server (#751)
* fix(python): expose client capabilities to MCP servers Add list_roots_callback support to Python connectors to properly advertise the roots capability during MCP initialization handshake. Previously, the Python library was not exposing any client capabilities because the list_roots_callback was not being passed to ClientSession. This fix ensures the roots capability is always advertised, bringing the Python library in line with the TypeScript implementation. Changes: - Add roots and list_roots_callback params to BaseConnector - Add get_roots() and set_roots() methods for managing roots - Pass list_roots_callback to ClientSession in all connectors - Export Root type from connectors module - Update unit tests to expect list_roots_callback parameter Closes MCP-1063 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * feat(python): add roots and list_roots_callback params to connectors - Add roots and list_roots_callback parameters to StdioConnector, HttpConnector, and SandboxConnector constructors - Add comprehensive unit tests for client capabilities exposure - Tests verify roots capability, get_roots(), set_roots(), and that all callbacks are correctly passed to ClientSession 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * chore: fix import sorting and update API documentation - Fix import sorting in test_client_capabilities.py (ruff) - Regenerate API documentation for updated connector classes 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * feat(python): add list_roots() method to server Context Allow MCP servers to request the list of roots from connected clients via ctx.list_roots(). This follows the same pattern as ctx.sample() and ctx.elicit() for server-to-client requests. * feat(python): add roots params to MCPClient and config - Add roots and list_roots_callback parameters to MCPClient.__init__, from_dict(), and from_config_file() methods - Update create_connector_from_config() to pass roots params to all connector types (Stdio, HTTP, Sandbox) - Allows clients to configure roots at the MCPClient level and have them propagate to all sessions * test(python): add get_client_roots tool to primitive server Add a tool that demonstrates the roots capability by requesting and returning the list of roots from the connected client. Used for integration testing of the roots feature. * test(python): add integration tests for roots capability Add comprehensive integration tests for the roots feature: - test_roots_capability: Verify server can request/receive roots - test_roots_empty_by_default: Verify empty roots when not provided - test_roots_with_custom_callback: Verify custom callback precedence - test_set_roots_updates_server_view: Verify dynamic root updates * test(python): update unit tests for roots parameters Update mock assertions in test_client.py to expect the new roots and list_roots_callback parameters in create_connector_from_config calls. * ci(python): add roots to primitive tests and README badge - Add roots to CI workflow primitive test matrix - Add roots to PR comment report primitives list - Add Roots badge to README Primitives row * feat(docs): enhance MCP client and server documentation for roots feature - Added `roots` and `list_roots_callback` parameters to MCP client initialization documentation. - Updated `create_connector_from_config` documentation to include new parameters. - Introduced `list_roots` method documentation in server context, detailing its usage and return values. - Improved overall clarity and completeness of API reference for better developer guidance. * feat(python): add get_client_roots tool to context example - Introduced a new tool, `get_client_roots`, to the context example, demonstrating how to retrieve and display the list of roots exposed by the client. - Updated documentation to include the new tool and its functionality, enhancing the example's coverage of context features. * feat(docs): add roots documentation for client and server - Introduced new documentation for the `roots` feature, detailing how clients can expose file system roots to MCP servers and how servers can access these roots. - Added examples for configuring roots in the MCP client and using the `list_roots()` method in the server context. - Enhanced overall clarity and usability of the documentation to support developers in implementing the roots functionality. --------- Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com> Co-authored-by: pietrozullo <pietro.zullo@gmail.com> |
