The same atlas, over an API and an MCP server

1. Make a key

Sign in, open Settings, create a key. It starts with sa_ and is shown once. Public reads need no key.

2. MCP

Streamable HTTP at https://systematlas.org/mcp. Claude Code:

claude mcp add --transport http system-atlas https://systematlas.org/mcp \
  --header "Authorization: Bearer sa_…"

Any MCP client config:

{
  "mcpServers": {
    "system-atlas": {
      "type": "http",
      "url": "https://systematlas.org/mcp",
      "headers": { "Authorization": "Bearer sa_…" }
    }
  }
}

3. HTTP API

curl https://systematlas.org/api/v1/industries
curl https://systematlas.org/api/v1/industries/staffing
curl "https://systematlas.org/api/v1/search?q=payroll"
curl https://systematlas.org/api/v1/glossary

# with a key
curl -H "Authorization: Bearer sa_…" https://systematlas.org/api/v1/workspaces
curl -H "Authorization: Bearer sa_…" https://systematlas.org/api/v1/workspaces/acme-builders
curl -H "Authorization: Bearer sa_…" \
  "https://systematlas.org/api/v1/workspaces/acme-builders/companies/client?public=1"
curl -H "Authorization: Bearer sa_…" \
  "https://systematlas.org/api/v1/workspaces/acme-builders/compare?with=rival-construction-co"

Responses are { data } or { error: { code, message } } with the matching HTTP status.

Tools and endpoints

• list_industriesIndustries with a published schema.public
• get_schemaAn industry's primitives, parameters, modules and connection types.public
• searchSearch primitives and modules by name.public
• get_glossaryThe ontology, every term defined.public
• list_workspacesWorkspaces the key can reach.needs key
• get_workspaceCompanies, completeness, layer health and top gaps.needs key
• get_company_atlasComponents, values with sources and confidence, edges and notes.needs key
• compareClient against competitors, one row per primitive, ranked by delta.needs key

What an agent can do with it

• Design against real structure. Pull an industry schema and a client atlas, then propose the modules and interfaces that close the ranked gaps.
• Run comparative analysis. Compare a client against every mapped competitor and write the debrief, citing the source behind each value.
• Keep the vocabulary straight. The glossary tool gives the agent the ontology, so its output uses the same terms the consultant and the client use.
• Respect the tiers. Private values never leave a workspace the key cannot access, and every private read is in the owner's audit log.

Writes (adding components, values and notes from an agent) and the research agent that drafts a company from public sources are next.
