From c99c42e002ec9f5e17ee2d0b836579ed5649f542 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Martin=20Va=C5=A1ko?= Date: Mon, 2 Feb 2026 09:51:26 +0100 Subject: [PATCH 01/11] feat: add role-based authorization for guest and read-only users Implements read-only tool access restrictions for guest and read-only roles to enable safe in-platform chat access with limited permissions. Changes: - Add role detection helpers (is_guest_role, is_read_only_role, requires_read_only_access) - Filter tools list to show only read-only tools for guest/read roles - Block write tool execution with clear error messages - Add comprehensive test suite (35 tests) for role-based authorization - Update README with role-based access control documentation Guest and read-only users now have access to 15 read-only tools only: get_jobs, get_buckets, get_tables, get_project_info, docs_query, query_data, search, find_component_id, get_data_apps, get_components, get_configs, get_config_examples, get_flows, get_flow_examples, get_flow_schema Co-Authored-By: Claude Sonnet 4.5 --- README.md | 11 + src/keboola_mcp_server/mcp.py | 48 ++++ tests/test_role_based_authorization.py | 294 +++++++++++++++++++++++++ tests/test_server.py | 2 + 4 files changed, 355 insertions(+) create mode 100644 tests/test_role_based_authorization.py diff --git a/README.md b/README.md index bc540548..f9933e8a 100644 --- a/README.md +++ b/README.md @@ -124,6 +124,17 @@ X-Read-Only-Mode: true For detailed documentation, see [developers.keboola.com/integrate/mcp/#tool-authorization-and-access-control](https://developers.keboola.com/integrate/mcp/#tool-authorization-and-access-control). +#### Role-Based Access Control + +The MCP Server automatically restricts tool access based on your Keboola token role: + +- **Guest Role**: Users with guest role can only access read-only tools +- **Read Role**: Similar to guest, read-only users are restricted to query-only operations +- **Admin Role**: Full access to all tools including modifications +- **Other Roles**: Standard access with some administrative restrictions + +The role is determined by your Storage API token and automatically enforced. + --- ## Local MCP Server Setup (Custom or Dev Way) diff --git a/src/keboola_mcp_server/mcp.py b/src/keboola_mcp_server/mcp.py index 5e5b0255..e13b2c2e 100644 --- a/src/keboola_mcp_server/mcp.py +++ b/src/keboola_mcp_server/mcp.py @@ -258,6 +258,12 @@ class ToolsFilteringMiddleware(fmw.Middleware): The middleware also intercepts the `on_call_tool()` call and raises an exception if a call is attempted to a tool that is not available in the current project. + + Role-based access control: + - Admin: Full access to all tools + - Guest: Read-only access (only tools with readOnlyHint=True) + - Read: Read-only access (only tools with readOnlyHint=True) + - Other roles: Standard access (write tools available) """ @staticmethod @@ -282,6 +288,33 @@ def get_token_role(token_info: JsonDict) -> str: return role return '' + @staticmethod + def is_guest_role(token_info: JsonDict) -> bool: + """Check if the token belongs to a guest user.""" + role = ToolsFilteringMiddleware.get_token_role(token_info).lower() + return role == 'guest' + + @staticmethod + def is_read_only_role(token_info: JsonDict) -> bool: + """Check if the token belongs to a read-only user.""" + role = ToolsFilteringMiddleware.get_token_role(token_info).lower() + return role == 'read' + + @staticmethod + def requires_read_only_access(token_info: JsonDict) -> bool: + """Check if the token requires read-only tool access.""" + return ( + ToolsFilteringMiddleware.is_guest_role(token_info) + or ToolsFilteringMiddleware.is_read_only_role(token_info) + ) + + @staticmethod + def _is_read_only_tool(tool: Tool) -> bool: + """Check if a tool has readOnlyHint=True annotation.""" + if tool.annotations is None: + return False + return tool.annotations.readOnlyHint is True + @staticmethod def is_client_using_main_branch(ctx: Context) -> bool: """ @@ -315,6 +348,11 @@ async def on_list_tools( # Filter out data app tools when the client is not using the main/production branch tools = [t for t in tools if t.name not in {'modify_data_app', 'get_data_apps', 'deploy_data_app'}] + # Role-based filtering: read-only access for guest and read roles + if self.requires_read_only_access(token_info): + tools = [t for t in tools if self._is_read_only_tool(t)] + LOG.info(f'Read-only access: filtered to {len(tools)} read-only tools for role={token_role}') + return tools async def on_call_tool( @@ -327,6 +365,16 @@ async def on_call_tool( features = self.get_project_features(token_info) token_role = self.get_token_role(token_info).lower() + # Block non-read-only tools for guest and read-only roles + if self.requires_read_only_access(token_info): + if not self._is_read_only_tool(tool): + LOG.info(f'Tool access denied: {tool.name} is not read-only for role={token_role}') + raise ToolError( + f'Access denied: The tool "{tool.name}" requires write permissions.

Create utils.py with shared is_read_only_tool() function - Remove duplicate _is_read_only_tool() from authorization.py and mcp.py - Remove unnecessary wrapper functions (is_guest_role, is_read_only_role, requires_read_only_access) - Use direct inline checks: if token_role in ['guest', 'readonly'] - Fix case sensitivity bug: readOnly -> readonly (to match .lower() conversion) - Change INFO to DEBUG logging for frequent operations Addresses PR #381 review feedback on code simplification and deduplication.

This prevented developers from running integration tests locally on non-US environments. Changes: - Add region-aware fixtures (hostname_suffix, connection_url, queue_url, ai_url, links_manager) to integtests/conftest.py - Replace hardcoded URLs in test assertions with dynamic fixtures - Use ProjectLinksManager for URL generation (same abstraction used in source code) - Fix flow conftest to properly delete configurations (double-delete for permanent removal) Tests now work on any Keboola region without code modification.
