mcp-writer-substack
The Writer Context Tool for Claude is an open-source MCP server designed to connect Claude to content from Substack and Medium. It retrieves, caches, and allows semantic search of your blog posts to assist with personalized writing support.
What should I do if the tool doesn't appear in Claude Desktop?
Check that your Claude Desktop configuration file is correct, verify that all paths in the configuration are absolute, ensure your Python environment has all required packages, and restart Claude Desktop.
What if no content appears?
Verify your Substack/Medium URLs in config.json, try using the 'refresh_content' tool, and check that your blogs are public and have published posts.
What should I do if there's an error with the uv command?
Try using the shell script approach instead, and verify the uv command is installed and in your PATH.
What if there are embedding issues?
Ensure you have enough disk space, and consider rerunning with a fresh installation if embeddings aren't working properly.
