pctx MCP server

pctx is the execution layer for agentic tool calls. It auto-converts agent tools and MCP servers into code that runs in secure sandboxes for token-efficient workflows.

What pctx does

Summarised from the project README; check the repository for the latest details.

Features

• Code Mode interface: Tools exposed as code functions for efficient agent interaction. See Code Mode Guide.
• Upstream MCP server aggregation: Connect to multiple MCP servers through a single interface, with persistent upstream sessions across `executetypescript` calls. See Upstream MCP Servers Guide.
• Simple config with CLI: Create the pctx.json config with a simple CLI. pctx.json manages auth, upstream MCPs, logging, and more. See Config Guide.
• Secure authentication: Source secrets from environment variables, system keychain, and external commands. See Authentication Section in the CLI configuration docs for more details.
