AI coding assistants often fail because they retrieve the wrong context. On a large codebase, blindly dumping raw files into the prompt leads to hallucinations, slow responses, and high API costs.
mcp-injector is an MCP project maintained in the foldwork-dev/mcp-injector repository. The maintainer describes its purpose as “AI coding assistants often fail because they retrieve the wrong context. On a large codebase, blindly dumping raw files into the prompt leads to hallucinations…”. Read the project documentation for the complete scope.
The project provides a local client configuration using /usr/local/bin/mcp-injector. Follow the repository’s build and installation steps before copying it, and replace example paths with the paths on your own computer.
The example declares MCP_WORKSPACE, FOLDWORK_DB_DSN. Secret-looking values have been replaced with placeholders. Required and optional labels are shown only when the documentation states them.

Store entities, relations and observations in a local knowledge graph with the reference Memory MCP server.
Connect the Notion MCP server to search workspace content and work with pages and databases through Notion’s hosted OAuth service.
Search Linear issues and projects, inspect work context and manage updates through Linear’s hosted MCP server with OAuth.
Your assistant inside the workspace — read channels, search history, post messages and tame the noise.
Metabase ships its own MCP endpoint — search your BI content, build and run queries, and save questions and dashboards without leaving the chat.
Stop letting your assistant hallucinate n8n node parameters — this server hands it the real schemas, templates and validation.
