Filesystem, Fetch, Memory, and Shell servers implementing the Model Context Protocol 2026-07-28 specification over stdio.
Secure read/write access to a set of allowed directories: read, write, edit, search, tree listings, file info, and more, with path and symlink protection.
Fetches URLs and converts HTML pages to markdown for the model, with robots.txt enforcement, truncation pagination, and a user-initiated fetch prompt.
Persistent knowledge-graph memory (entities, relations, observations) stored as JSONL, exposed through tools, a resource, and live subscriptions.
Executes local programs directly with an explicit argv, a restricted working directory, bounded output capture, and a per-command timeout.
Stateless MCP 2026-07-28 via rmcp: server/discover without an initialize handshake, cache hints on tools/list, and tool annotations.
Offline integration suites cover every parameter and access-control edge; a gated real-network OpenRouter acceptance suite exercises the whole stack.
