Graphlit

configureProject

Configures the default content workflow and conversation specification for the Graphlit project. Only needed if user asks to configure the project defaults. *Do not* call unless specifically asked for by the user. To reset the project configuration to 'factory state', assign False or null to all parameters. Optionally accepts whether to configure the default specification for LLM conversations. Defaults to using OpenAI GPT-4o, if not assigned. Optionally accepts whether to enable high-quality document and web page preparation using a vision LLM. Defaults to using Azure AI Document Intelligence for document preparation, if not assigned. Optionally accepts whether to enable entity extraction using LLM into the knowledge graph. Defaults to no entity extraction, if not assigned. Optionally accepts the preferred model provider service type, i.e. Anthropic, OpenAI, Google. Defaults to Anthropic if not provided. Returns the project identifier.

queryProjectUsage

Queries project usage records. Usage record name describes the operation, i.e. 'Prompt completion', 'Text embedding', 'GraphQL', 'Entity Event'. 'GraphQL' usage records are used for GraphQL operations, i.e. 'queryContents', 'retrieveSources', 'askGraphlit', etc. 'Entity Event' usage records are used for async compute operations. 'Text embedding' usage records are used for text embedding operations. 'Prompt completion' usage records are used for LLM prompt completion operations, i.e. when using 'promptConversation'. 'Data extraction' usage records are used for data extraction operations, using LLMs to extract knowledge graph entities. Look at 'metric' field for the type of metric captured in the usage record, i.e. BYTES, TOKENS, UNITS, REQUESTS. Look for 'credits' field which describes how many credits were charged by the operation. Look for 'promptTokens', 'completionTokens' and (total) 'tokens' fields which describe the number of tokens used by the operation. Look for 'request', 'response' and 'variables' fields which describe the GraphQL operation. Look for 'count' for the number of units used by the operation, for example, number of pages processed by document preparation. Accepts an optional recency filter for usage records 'in last' timespan. Returns a list of usage records, which describe the billable audit log of all Graphlit API operations.

askGraphlit

Ask questions about using the Graphlit Platform, or specifically about the Graphlit API or SDKs. When the user asks about how to use the Graphlit API or SDKs, use this tool to provide a code sample in Python, TypeScript or C#. Accepts an LLM user prompt. Returns the LLM prompt completion in Markdown format.

promptConversation

Prompts an LLM conversation about your entire Graphlit knowledge base. Uses hybrid vector search based on user prompt for locating relevant content sources. Uses LLM to complete the user prompt with the configured LLM. Maintains conversation history between 'user' and LLM 'assistant'. Prefer 'promptConversation' when the user intends to start or continue an ongoing conversation about the entire Graphlit knowledge base. Similar to 'retrieveSources' but does not perform content metadata filtering. Accepts an LLM user prompt and optional conversation identifier. Will either create a new conversation or continue an existing one. Will use the default specification for LLM conversations, which is optionally configured with the 'configureProject' tool. Returns the conversation identifier, completed LLM message, and any citations from the LLM response.

retrieveSources

Retrieve relevant content sources from Graphlit knowledge base. Do *not* use for retrieving content by content identifier - retrieve content resource instead, with URI 'contents://{id}'. Accepts an LLM user prompt for content retrieval. For best retrieval quality, provide only key words or phrases from the user prompt, which will be used to create text embeddings for a vector search query. Only use when there is a valid LLM user prompt for content retrieval, otherwise use 'queryContents'. For example 'recent content' is not a useful user prompt, since it doesn't reference the text in the content. Only use for 'one shot' retrieval of content sources, i.e. when the user is not interested in having a conversation about the content. Accepts an optional ingestion recency filter (defaults to null, meaning all time), and optional content type and file type filters. Also accepts optional feed and collection identifiers to filter content by. Returns the ranked content sources, including their content resource URI to retrieve the complete Markdown text.

Returns the matching images, including their content resource URI to retrieve the complete Markdown text.

extractText

Extracts JSON data from text using LLM. Accepts text to be extracted, and JSON schema which describes the data which will be extracted.
