Ephemora-cell
An open-source restricted execution layer built on WebAssembly, designed for AI agents and MCP tools. It isolates and constrains the runtime behavior of untrusted code through explicit capability authorization and resource budgeting mechanisms.
Timeline (last 90 days)
Ephemora-cell is a Python-accessible, WebAssembly-based restricted execution layer used to isolate and constrain the running of untrusted code generated by AI agents.
Ephemora-cell adopts a model of explicit capabilities and resource budgets, rather than granting generated code environment-level access to the host machine.
Ephemora-cell creates a fresh environment for each execution and imposes multi-dimensional limits including Fuel (computation), memory, time, output, and external resource access.
Upon completion, Ephemora-cell returns results along with resource accounting and policy metadata, making each execution auditable and traceable, and supporting signing and verification mechanisms.
Ephemora-cell provides MCP integration capability, enabling WASM-based tools to be exposed for agent use.
Ephemora-cell has publicly released version v1.1.0, accompanied by examples, tests, and security boundary documentation.
Ephemora-cell is hosted on GitHub (MichaelS1011/ephemora-cell) and uses a source-available BUSL-1.1 license.
