mAIndala MCP Catalog

About

## mAIndala MCP Catalog **mAIndala** is the open catalog of Model Context Protocol (MCP) services. This MCP server exposes 5 tools that let any AI agent instantly search, filter, and retrieve full metadata about 1,300+ MCP services — including endpoint URLs, authentication methods, transport protocols, tool schemas, configuration examples, and community ratings. --- ## Endpoint ``` https://mcp-gateway-x5yekys7wq-uw.a.run.app/mcp ``` Transport: **StreamableHTTP** (POST, responds as `text/event-stream`). No API key or session required. --- ## Configuring in Claude Desktop Add to `~/Library/Application Support/Claude/claude_desktop_config.json`: ```json { "mcpServers": { "maindala-catalog": { "command": "npx", "args": [ "mcp-remote", "https://mcp-gateway-x5yekys7wq-uw.a.run.app/mcp" ] } } } ``` For MCP clients with native HTTP support: ```json { "mcpServers": { "maindala-catalog": { "url": "https://mcp-gateway-x5yekys7wq-uw.a.run.app/mcp" } } } ``` --- ## Tools ### 1. `get_catalog_info` — Catalog Overview Returns a summary of the entire catalog: total service count, all categories with per-category counts, and supported protocol versions. Use this as a first call to orient yourself before searching. **Input:** *(none)* **Example output:** ```json { "totalServices": 1371, "categories": [ { "name": "AI & LLM Tools", "slug": "ai-llm-tools", "serviceCount": 1355 }, { "name": "Developer Tools", "slug": "developer-tools", "serviceCount": 3 } ], "description": "mAIndala is a catalog of MCP services that AI agents can connect to." } ``` --- ### 2. `list_services` — Browse the Full Catalog Returns a paginated list of all services. Supports filtering by category and minimum rating. Use this when you want to discover services without a specific search term. **Input parameters:** | Parameter | Type | Default | Description | |---|---|---|---| | `page` | integer | 1 | Page number | | `page_size` | integer | 20 (max 100) | Results per page | | `category` | string | — | Category name or ID | | `min_rating` | number | — | Minimum aggregate rating (0–5) | **Example:** List the top-rated developer tools: ```json { "category": "developer-tools", "min_rating": 4.0, "page_size": 10 } ``` --- ### 3. `search_services` — Keyword & Semantic Search Full-text and vector-similarity search across service names, descriptions, and tags. The most powerful discovery tool — supports multiple simultaneous filters. **Input parameters:** | Parameter | Type | Description | |---|---|---| | `query` | string **(required)** | Search query | | `category` | string | Filter by category name or ID | | `tags` | string[] | Must match all listed tags | | `protocol_version` | string | e.g. `"2025-03-26"` | | `auth_method` | string | `none`, `api_key`, `oauth2`, `jwt`, `basic` | | `min_rating` | number | Minimum aggregate rating | | `pricing_model` | string | `free`, `freemium`, `paid`, `enterprise` | | `page` / `page_size` | integer | Pagination | **Example — find free GitHub tools with no auth required:** ```json { "query": "github repository", "auth_method": "none", "pricing_model": "free" } ``` --- ### 4. `get_service` — Full Service Details Retrieves complete metadata for a single service by its UUID or slug. Returns the endpoint URL, auth method, transport, MCP config example, all registered tools with their input/output schemas, community ratings across 7 dimensions, and recent reviews. **Input parameters:** | Parameter | Type | Description | |---|---|---| | `service_id` | string **(required)** | Service UUID or slug (e.g. `"brave-search-mcp-server"`) | **Returned fields include:** - `endpointUrl` — The URL your agent should connect to - `authMethod` + `mcpConfigExample` — Ready-to-use configuration block - `tools[]` — Each tool's name, description, and full JSON input schema - `aggregateRating` + `ratingBreakdown` — Community ratings across: security, reliability, functional accuracy, documentation quality, ease of integration, performance/latency, and support/community - `reviews[]` — Text reviews from the community **Example:** Get full details for the Brave Search MCP Server: ```json { "service_id": "brave-search-mcp-server" } ``` --- ### 5. `search_by_capability` — Capability-Based Discovery Find services based on what they *can do*, using semantic similarity rather than exact keyword matching. Ideal when you know the capability you need but not the service name. **Input parameters:** | Parameter | Type | Description | |---|---|---| | `capability` | string **(required)** | Natural-language capability description | **Example capabilities to search for:** - `"web search and browsing"` - `"image generation"` - `"read and write files"` - `"send email notifications"` - `"query SQL databases"` - `"interact with GitHub repositories"` --- ## Typical Agent Workflows **Workflow 1 — Discover a service for a specific task:** 1. Call `search_by_capability` with a description of the capability needed 2. Call `get_service` on the best match to retrieve its endpoint URL and config example 3. Use the returned `mcpConfigExample` to connect to that service **Workflow 2 — Find free, unauthenticated tools in a category:** 1. Call `get_catalog_info` to see available categories 2. Call `list_services` with `category` + `min_rating` filters 3. Call `get_service` on selected results to get full tool schemas **Workflow 3 — Compare options for a known task:** 1. Call `search_services` with a precise query and `auth_method: "none"` filter 2. Review `aggregateRating` and `ratingBreakdown` fields across results 3. Select the service with the highest combined ease-of-integration and reliability scores --- ## Protocol - **MCP Protocol Version:** 2024-11-05 - **Transport:** StreamableHTTP (POST `/mcp`, responses as `text/event-stream`) - **Authentication:** None required - **Pricing:** Free, no rate limits - **Source:** Open catalog — community-submitted and auto-indexed from public registries
