When a tool like `gzip-file-as-resource` is called multiple times with the same output name (especially the default `README.md.gz`), the server would throw "Resource already registered" because the SDK doesn't allow registering duplicate URIs. This fix: - Tracks registered resources by URI in a module-level Map - Before registering a new resource, checks if the URI already exists - If it does, removes the old resource using the SDK's `remove()` method - Then registers the new resource with fresh content This allows tools to be called repeatedly with the same parameters without errors, which is important for LLM agents that may retry tool calls. Found using Bellwether (https://bellwether.sh), an MCP server validation tool. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
The httpx library renamed 'proxies' to 'proxy' in version 0.28.0. This updates the fetch server to use the new parameter name and removes the version cap on httpx. Fixes #3287
…es/searchNodes Previously, `openNodes` and `searchNodes` only returned relations where BOTH endpoints were in the result set (using `&&`). This silently dropped all relations to/from nodes outside the set — making it impossible to discover a node's connections without calling `read_graph` and filtering the entire dataset client-side. Changed the filter from `&&` to `||` so that any relation with at least one endpoint in the result set is included. This matches the expected graph-query semantics: when you open a node, you should see all its edges, not just edges to other opened nodes. Fixes #3137 Tests updated and new cases added covering: - Outgoing relations to nodes not in the open set - Incoming relations from nodes not in the open set - Relations connected to a single opened node - searchNodes returning outgoing relations to unmatched entities Co-authored-by: Cursor <cursoragent@cursor.com>
…ions fix(memory): return relations connected to requested nodes in openNodes/searchNodes
…tration fix(everything): allow re-registration of session resources
fix(fetch): update to httpx 0.28+ proxy parameter
