Retrieves details about a Notion entity by its URL or ID. You can fetch the following types of entities: - Page, i.e. from a <page> block or a <mention-page> mention - Database, i.e. from a <database> block or a <mention-database> mention Use the "fetch" tool when you need to see the details of a Notion entity you already know exists and have its URL or ID. Provide the Notion entity's URL or ID in the `id` parameter. You must make multiple calls to the "fetch" tool if you want to fetch multiple entities. Content for pages that are returned use the enhanced Markdown format, which is a superset of the standard Markdown syntax. See the full spec in the description of the "create-pages" tool. Databases can have multiple data sources, which are collections of pages with the same schema. When fetching a database, the tool will return information about all its data sources. Examples of fetching entities: 1. Fetch a page by URL: { "id": "https://www.notion.so/workspace/Product-Requirements-1234567890abcdef" } 2. Fetch a page by ID (UUIDv4 with dashes): { "id": "12345678-90ab-cdef-1234-567890abcdef" } 3. Fetch a page by ID (UUIDv4 without dashes): { "id": "1234567890abcdef1234567890abcdef" } 4. Fetch a database: { "id": "https://www.notion.so/workspace/Projects-Database-abcdef1234567890" } Common use cases: - "What are the product requirements still need to be implemented from this ticket https://notion.so/page-url?" - "Show me the details of the project database at this URL" - "Get the content of page 12345678-90ab-cdef-1234-567890abcdef"

Find products with the highest agent readiness scores — products that are easiest for AI agents to integrate with. Sorted by compositeScore desc; supports skip/limit pagination. All readiness scores are 0-100, higher better. Calibration: <30 = not agent-ready (default minimumScore filter), 30-49 = early/limited, 50-69 = decent, 70-89 = strong, 90+ = exceptional. Response: array of { slug, name, tagline, websiteUrl, tier (free|verified|featured), unverified (true on free only), verifiedAt (ISO; nullable), agentReadiness: { compositeScore, apiScore, protocolScore, sdkScore, integrationScore, dxScore } (each 0-100), mcp?: { hasMcpSupport, totalToolCount, serverCount } }. Note: ordering is by agent-readiness, not by tier — this is the one MCP tool where tier doesn't reorder results, since the buyer intent is technical fit, not paid placement.

Discovers sections/categories across awesome lists matching a search query and returns matching sections from awesome lists. You MUST call this function before 'get_awesome_items' to discover available sections UNLESS the user explicitly provides a githubRepo or listId. Selection Process: 1. Analyze the query to understand what type of resources the user is looking for 2. Return the most relevant matches based on: - Name similarity to the query and the awesome lists section - Category/section relevance of the awesome lists - Number of items in the section - Confidence score Response Format: - Returns matching sections of the awesome lists with metadata - Includes repository information, item counts, and confidence score - Use the githubRepo or listId with relevant sections from results for get_awesome_items For ambiguous queries, multiple relevant sections will be returned for the user to choose from.

Find B2B SaaS products that support a specific capability — an integration with a named service ('salesforce-integration'), a data format ('xrechnung-support'), an industry standard ('eclass-support'), or a compliance certification ('soc2'). Accepts either a canonical capability slug or natural language; resolves to a structured capability when possible. Returns products ranked by tier (Featured > Verified > Free). Response: { capability, matchType (none|exactSlug|canonicalSlug|nlpFallback — exactSlug & canonicalSlug are deterministic; nlpFallback is heuristic), resolvedFeatures[], products[] }. Each product: { slug, name, tagline, websiteUrl, tier, unverified (true on free only), verifiedAt, evidence[] (per-claim: featureSlug, evidenceUrl, notes, source, confidence) }. Empty: { capability, matchType, message, suggestedSlugs[] } when no capability matched, or products: [] when capability matched but no products claim it yet.

Find the best MCP tools for a given task. Describe what you want to accomplish (e.g. 'manage github issues', 'send slack messages', 'query a database') and get ranked results with the products that provide each tool and their input schemas. By default only shows tools available via remote (network-hosted) servers. Audience: agent builders looking for installable MCP tools — for B2B SaaS recommendations, prefer search_products or find_products_with_capability. Response: { task, matchType (none|exactSlug|canonicalSlug|nlpFallback), resolvedCapabilities[], capabilityProducts[] (B2B SaaS products that claim the same capability — empty when matchType=none), results[] (MCP-tool-level matches) }. Each result: { normalizedName, displayName, description, inputSchema, relevance (integer; +1 per term hit, +3 for full-phrase hit), productCount, products[] (each: slug, name, serverQualifiedName, isRemoteCapable, tier, unverified, verifiedAt) }. Empty case: { task, matchType, message, suggestedQueries[], suggestedCapabilities[] }.
