README
PKB MCP Server
A Python MCP (Model Context Protocol) server that provides a Personal Knowledge Base backed by a GitHub repository. TIL entries, prompts, and patterns are stored as Markdown files and managed through a set of tools exposed via the MCP protocol.
Tools
The server exposes 5 tools:
| Tool | Description |
|---|---|
| add_til | Create a "Today I Learned" entry with a title, content, and tags. |
| add_prompt | Save a reusable prompt in a category (coding, infrastructure, documentation, general). |
| add_pattern | Document a reusable pattern in a category (agent, cloud, devops). |
| search_pkb | Search the entire knowledge base by keyword. |
| list_entries | Browse entries in a section (til, prompts, patterns, or all). |
Environment Variables
| Variable | Required | Description |
|---|---|---|
GITHUB_TOKEN |
Yes | A GitHub personal access token with Contents: Read and write permissions on the target repository. |
GITHUB_REPO |
No | The GitHub repository in owner/repo format. Defaults to pdawson1983/dawson-pkb. |
GitHub Token Setup
- Go to GitHub Settings > Developer settings > Fine-grained tokens.
- Click Generate new token.
- Give the token a descriptive name (e.g.
pkb-mcp-server). - Under Repository access, select the repository you want to use as your knowledge base.
- Under Permissions > Repository permissions, set Contents to Read and write.
- Click Generate token and copy the value.

Claude Desktop Integration
Add the following to your claude_desktop_config.json to use this server with Claude Desktop:
{
"mcpServers": {
"pkb": {
"command": "docker",
"args": ["run", "-i", "--rm", "-e", "GITHUB_TOKEN", "pkb-mcp-server"],
"env": {
"GITHUB_TOKEN": "your-github-token-here"
}
}
}
}
The GITHUB_REPO environment variable should be set inside the container (e.g. baked into the image or added to the args with an additional -e GITHUB_REPO=owner/repo flag).
