pwn-mcp-server

An MCP server for pulsar wind nebulae (PWNe) and other nebulae. It can:

  • query catalogs: a bundled curated PWN table, plus live SIMBAD, VizieR (Green SNR catalogue, H.E.S.S. HGPS, Sharpless, WISE H II, Strasbourg-ESO PNe), the ATNF pulsar catalogue and CADC
  • render survey images, including the Canadian Galactic Plane Survey (CGPS)
  • compare nebular colours under the CIE 1931 2° and CIE 1964 10° standard observers

Work in progress; see the commit history for the current state.
