sanka-cli

sanka-cli is Sanka's single Python distribution. It installs one sanka executable and contains:

• the Apache-2.0 hosted command dispatcher, authentication, output, and optional MCP integration under sanka_cli;
• the embedded Apache-2.0 Connector SDK under sanka_connector; and
• the AGPL-3.0-only local migration runtime under sanka.

Python 3.12 or newer is required.

Install

uv tool install sanka-cli
sanka --help

For the stdio MCP server:

uv tool install 'sanka-cli[mcp]'
sanka mcp

The base tool does not install framework migrations or provider drivers. Components are immutable GitHub release wheels selected through the extension manager:

sanka extension marketplace add https://github.com/sankaHQ/extensions.git --name sanka
sanka extension add sanka/drf-to-fastapi
sanka extension add sanka/markdown
sanka extension add sanka/sqlite

PyPI is not used as an extension fallback.

Local commands

sanka scan .
sanka plan .
sanka apply --plan-hash sha256:<hash-from-plan>
sanka test .
sanka verify .

Data migrations default to sanka.yaml:

source:
  type: markdown
  connection: ./content
target:
  type: sqlite
  connection: content.db

scan, marketplace management, extension installation, local planning, testing, and verification never require a Sanka API token. Hosted resources, workflows, AI, Custom Code, and explicitly cloud-selected migrations retain their existing authentication requirements. Add --json to local lifecycle commands for the stable sanka-cli/v1 response envelope.

Extension trust

The manager verifies a trusted marketplace snapshot, manifest schema, component/runtime compatibility, exact wheel URL and SHA-256 digest, package metadata, entry points, and installed files. Project locks record the exact snapshot and artifact identities in .sanka/extensions.lock.

Migration components use the sanka-extension/v1 subprocess protocol. Connector implementations load only in an isolated child environment and are proxied over sanka-connector/v1; provider code is never imported into the main CLI process. Hosted providers are not local connectors.

Python facade

from sanka import Sanka

Sanka.connect(...) creates a write-free endpoint descriptor. Sanka.migrate(...) creates or resumes a local lifecycle handle. Planning is destination-write-free, and apply requires the exact plan hash returned by plan.

SDK automation

The Python and Node sanka-sdk migration adapters invoke sanka <command> ... --json as a local subprocess. They do not call hosted execution for local commands, require an API token, auto-install this package, or replace its framework detection and safety defaults.

MCP tools

sanka mcp exposes sanka_research_eol, sanka_research_tco, sanka_research_compare, and sanka_assess. Public research and assessment remain credential-free; the MCP server does not execute migrations.
