Validates MCP tool definitions against the Model Context Protocol specification schema, checking for required fields, type correctness, and structural compliance. Uses JSON schema validation to ensure tool definitions conform to MCP standards before they are exposed to LLM clients, preventing runtime failures and protocol violations.
Unique: Specialized linter built specifically for MCP tool definitions rather than generic JSON validation, understanding MCP-specific constraints like tool naming conventions, input schema requirements, and Claude-specific tool metadata
vs alternatives: More targeted than generic JSON schema validators because it understands MCP semantics and can provide MCP-specific error messages and remediation guidance
Analyzes tool input parameter schemas for completeness, type safety, and usability issues. Checks for missing descriptions, ambiguous type definitions, undocumented required fields, and parameter naming inconsistencies that could confuse LLM clients when invoking tools.
Unique: Evaluates parameters specifically from the perspective of LLM usability — checking whether descriptions are clear enough for an LLM to understand and invoke correctly, not just whether they are syntactically valid
vs alternatives: Goes beyond generic schema validation by assessing parameter clarity and LLM-friendliness, whereas standard JSON schema validators only check structural correctness
Lints tool names, descriptions, and identifiers against MCP and industry best practices for naming conventions. Detects non-standard naming patterns, overly long or unclear tool names, and inconsistent naming styles across tool suites that could reduce discoverability or clarity for LLM clients.
Unique: Applies MCP-specific naming conventions and LLM discoverability heuristics rather than generic code style rules, understanding that tool names are part of the LLM's decision-making context
vs alternatives: Specialized for MCP tool naming rather than generic code linters, with rules tailored to how LLMs parse and understand tool names
Evaluates tool descriptions for clarity, completeness, and LLM-friendliness using heuristics like length, specificity, and presence of usage examples or caveats. Detects vague descriptions, missing context about tool behavior, and descriptions that lack sufficient detail for an LLM to make informed invocation decisions.
Unique: Assesses descriptions specifically for LLM comprehension rather than human readability, using heuristics tuned to how LLMs parse tool documentation to make invocation decisions
vs alternatives: Specialized for LLM-facing documentation quality rather than generic documentation linters, with metrics focused on clarity for AI clients
Validates tool output/response schemas for completeness and consistency, checking that response structures are well-defined, documented, and compatible with MCP expectations. Detects missing response descriptions, undefined response types, and inconsistent response structures across similar tools.
Unique: Validates response schemas from the perspective of LLM client expectations, ensuring responses are structured in ways that LLM clients can reliably parse and understand
vs alternatives: Goes beyond generic schema validation by checking response clarity and LLM-friendliness, whereas standard validators only check structural correctness
Analyzes tool definitions for external dependencies, required environment variables, API keys, and integration points, flagging missing or incomplete dependency declarations. Detects tools that reference external services without documenting authentication requirements or configuration needs.
Unique: Specifically designed for MCP tool deployment scenarios, checking for MCP-specific integration patterns like authentication, configuration, and external service requirements
vs alternatives: More targeted than generic dependency checkers because it understands MCP deployment contexts and can validate MCP-specific configuration patterns
Lints tool definitions for documentation of error conditions, edge cases, and failure modes. Detects tools that lack error documentation, missing information about rate limits or quotas, and undocumented failure scenarios that could surprise LLM clients.
Unique: Specifically checks for documentation of error conditions and edge cases that matter to LLM clients, ensuring LLMs understand when tools might fail or behave unexpectedly
vs alternatives: Specialized for LLM-facing error documentation rather than generic code quality checks, with focus on preventing LLM misuse of tools
Processes multiple MCP tool definitions in a single pass, aggregating linting results across an entire tool suite and providing consolidated reports. Enables cross-tool consistency checking, duplicate detection, and suite-wide quality metrics with configurable rule sets and output formats.
Unique: Designed for suite-wide linting with aggregated reporting rather than single-tool validation, enabling consistency checking and quality metrics across entire MCP tool collections
vs alternatives: More efficient than running individual linters on each tool because it processes the entire suite in one pass and provides cross-tool consistency analysis

Executes SQL queries against Supabase PostgreSQL instances through the Model Context Protocol, translating natural language or structured query requests into parameterized SQL statements. Uses MCP's tool-calling interface to expose database operations as callable functions with schema validation, enabling LLM agents to perform CRUD operations, joins, and aggregations with automatic connection pooling and credential management through Supabase client SDK.
Unique: Exposes Supabase PostgreSQL as MCP tools with automatic credential injection from Supabase client SDK, eliminating manual connection string management and enabling seamless LLM-to-database queries within Claude or compatible agents
vs alternatives: Tighter integration than generic SQL MCP servers because it leverages Supabase's built-in authentication and connection pooling rather than requiring separate database credential configuration
Exposes Supabase Auth session state and user metadata through MCP tools, allowing agents to inspect current authentication context, retrieve user profiles, and trigger auth-related operations. Integrates with Supabase's JWT-based auth system to validate sessions and access user claims without re-authenticating, using the Supabase client's built-in session management.
Unique: Integrates Supabase's JWT-based auth system directly into MCP tool interface, allowing agents to inspect and act on auth state without managing separate credential stores or re-authentication flows
vs alternatives: More seamless than generic auth MCP servers because it leverages Supabase's built-in session management and avoids redundant credential passing between agent and auth system
Invokes Supabase Edge Functions (serverless TypeScript/JavaScript functions) through MCP tools, passing parameters and receiving results with optional streaming support. Uses Supabase's edge function HTTP API to trigger functions with automatic authentication headers and response parsing, enabling agents to execute custom business logic without embedding it in the agent itself.
Supabase scores higher at 42/100 vs mcp-tool-lint at 25/100.

Unique: Exposes Supabase Edge Functions as MCP tools with automatic authentication and response parsing, allowing agents to invoke custom serverless logic without managing HTTP clients or credential injection
vs alternatives: More integrated than generic HTTP MCP tools because it handles Supabase-specific authentication, error handling, and response formatting automatically
Subscribes to real-time changes on Supabase tables through MCP's event streaming interface, using Supabase's PostgreSQL LISTEN/NOTIFY mechanism to push INSERT, UPDATE, and DELETE events to agents. Maintains persistent WebSocket connections and filters events by table and row-level policies, enabling agents to react to database changes without polling.
Unique: Bridges Supabase's PostgreSQL LISTEN/NOTIFY real-time system with MCP's tool interface, enabling agents to subscribe to database changes without managing WebSocket connections or event serialization
vs alternatives: More efficient than polling-based approaches because it uses Supabase's native real-time infrastructure rather than repeated database queries
Manages files in Supabase Storage buckets through MCP tools, supporting upload, download, list, and delete operations with automatic authentication and path-based access control. Uses Supabase's S3-compatible storage API with built-in support for public/private buckets and signed URLs for temporary access, enabling agents to handle file I/O without managing cloud storage credentials.
