Implements a schema-based knowledge graph that stores entities, relations, and observations in a local JSON file, enabling structured semantic memory without requiring external databases. Uses MCP's Tool primitive to expose create/read/update/delete operations for graph nodes and edges, with automatic file serialization on each mutation. The architecture treats the JSON file as a single source of truth, avoiding distributed state complexity while maintaining ACID-like guarantees through synchronous writes.
Unique: Uses MCP's Tool primitive to expose graph operations as first-class LLM-callable functions, allowing the LLM to directly mutate its own knowledge graph rather than requiring external API calls. Stores graph as normalized JSON with entity deduplication and relation indexing by source/target, enabling the LLM to reason over graph structure.
vs alternatives: Simpler and faster to deploy than vector-DB-backed RAG systems (no embedding model required), and provides explicit entity/relation semantics that LLMs can reason about directly, unlike opaque vector similarity search.
Extends the knowledge graph with an observations layer that tracks when facts were learned, from which source, and with what confidence. Each observation is a timestamped assertion that can reference entities and relations, enabling the LLM to reason about fact provenance and recency. The architecture supports multiple observations per entity (e.g., 'user prefers coffee' observed on 2024-01-15 vs 2024-02-20), allowing the LLM to detect contradictions or track preference changes over time.
Unique: Treats observations as first-class graph primitives with explicit timestamps and confidence scores, rather than storing facts as immutable assertions. This enables the LLM to reason about fact uncertainty and temporal evolution, supporting use cases like tracking user preference changes or detecting contradictions across sources.
vs alternatives: More explicit about fact provenance than simple vector embeddings, and supports temporal reasoning that pure knowledge graphs without observation metadata cannot provide.
Exposes the knowledge graph through MCP's Tool primitive, allowing LLMs to query and mutate the graph using natural language descriptions that are translated into structured tool calls. The server defines tools like 'add_entity', 'add_relation', 'query_entities', 'get_relations' that accept JSON payloads and return structured results. This design treats the LLM as a first-class graph client, enabling it to reason about its own memory state and make deliberate updates without requiring external orchestration.
Unique: Uses MCP's Tool primitive to make graph operations first-class LLM capabilities, rather than hiding them behind a retrieval-augmented generation layer. The LLM can directly call tools to query and update its memory, enabling explicit reasoning about what it knows and what it should remember.
vs alternatives: More transparent and controllable than implicit RAG systems where the LLM doesn't know what facts are being retrieved. Enables the LLM to reason about its own memory state and make deliberate decisions about what to store.
Implements a typed relation system where edges between entities carry semantic meaning (e.g., 'user_prefers', 'works_at', 'knows'). Relations are stored as first-class graph objects with source entity, target entity, and relation type, enabling the LLM to reason about entity connections and traverse the graph semantically. The architecture supports both directed and undirected relations, and allows querying all relations of a given type or all relations involving a specific entity.
Unique: Uses typed relations as explicit graph edges with semantic meaning, rather than storing relationships as unstructured text observations. This enables the LLM to reason about entity connectivity and perform graph traversals, supporting use cases like finding common connections or detecting relationship chains.
vs alternatives: More structured and queryable than storing relationships as free-text observations, and enables explicit graph reasoning that pure entity-based systems cannot provide.
Persists the entire knowledge graph to a single local JSON file using synchronous writes, ensuring that every graph mutation is immediately durable. The architecture reads the entire file into memory on startup, performs mutations in-memory, and writes the complete updated graph back to disk on each operation. This design trades write latency for simplicity and ACID-like guarantees, avoiding the complexity of distributed consensus or transaction logs.
Unique: Uses simple synchronous file writes instead of a database, trading write latency for zero infrastructure overhead. The entire graph is stored in a single human-readable JSON file, enabling easy inspection and backup without requiring database tools.
vs alternatives: Simpler to deploy and debug than database-backed solutions, and enables human inspection of graph state. However, slower and less scalable than proper databases for large graphs or high-concurrency workloads.
Implements the MCP server lifecycle using the official TypeScript SDK, handling server initialization, tool registration, request routing, and graceful shutdown. The server exposes tools through MCP's standardized Tool primitive, registers them with the MCP host during initialization, and routes incoming tool calls to handler functions. The architecture follows MCP's request-response pattern, where each tool call is a JSON-RPC request that the server processes and returns a result.
Unique: Uses the official MCP TypeScript SDK to implement server lifecycle and tool registration, following the reference implementation pattern established by the MCP project. This ensures compatibility with MCP clients and demonstrates best practices for MCP server development.
vs alternatives: Official SDK provides type safety and handles protocol details automatically, reducing boilerplate compared to implementing JSON-RPC manually. However, adds SDK dependency and abstraction overhead.
Manages entity identity by storing entities with unique IDs and supporting name-based lookups to prevent duplicate entities from being created. When the LLM references an entity by name, the server checks if an entity with that name already exists before creating a new one. The architecture uses a simple name-to-ID mapping, enabling the LLM to refer to entities consistently across multiple conversations without creating duplicates.
Unique: Implements simple name-based entity deduplication without requiring external entity resolution services. The server maintains a name-to-ID mapping that prevents duplicate entities while allowing the LLM to refer to entities by name.
vs alternatives: Simpler than entity linking systems that use embeddings or external knowledge bases, but less robust to name variations. Suitable for closed-world applications with known entity sets.
Provides access to the raw knowledge graph state through the JSON file, enabling developers and LLMs to inspect what facts have been learned and how they're organized. The entire graph is stored in a human-readable JSON format with clear entity, relation, and observation structures. This design supports debugging by allowing developers to read the file directly, and enables LLMs to reason about their own memory state by querying the graph structure.
Unique: Stores the entire knowledge graph in a single human-readable JSON file, enabling direct inspection without requiring database tools or query languages. This design prioritizes transparency and debuggability over query performance.
vs alternatives: More transparent and debuggable than opaque database storage, but less queryable than systems with proper query languages or visualization tools.
Exposes Vercel API endpoints to list all projects associated with an authenticated account, retrieving project metadata including name, ID, creation date, framework detection, and deployment status.
