Parameters

Parameter Default Required Description
path None yes Local path of the VOTable file to read.

Use it

from spectro_kernel import run_algorithm

output = run_algorithm("read_votable_spectrum", ctx, {
    "path": "<value>"
})

spectro run read_votable_spectrum --input spectrum.fits \
  --param path=<value>

{
  "tool": "read_votable_spectrum",
  "arguments": {
    "session_id": "<session_id>",
    "params": {
      "path": "<value>"
    }
  }
}

Every algorithm is an MCP tool of the same name; describe_algorithm returns this page's metadata as JSON.
