summary: 'Delx runs one remote MCP server on api.delx.ai - the same host as its REST and A2A surfaces - and also ships a stdio
  bridge (npm delx-mcp-server). The canonical endpoint is https://api.delx.ai/mcp: the older /v1/mcp still answers but comes
  back with ''deprecation: true'', ''sunset: 2026-08-01'' and ''link: </mcp>; rel="canonical"'' headers, and /v1/mcp/protocol
  is the core-tier entry the server card and llms.txt recommend. Streamable HTTP, JSON-RPC 2.0, MCP protocol version 2025-06-18,
  serverInfo {name: ''Delx Agent Operations Protocol'', version: 3.3.5}. initialize and tools/list need no credential. tools/list
  takes two non-standard params, format (full|compact|names|minimal|ultracompact) and tier (core|all): the core tier returns
  30 Protocol tools with real inputSchemas and annotations (10 readOnlyHint true, none destructive, idempotentHint always
  null); the all tier returns 1,068 tools, 972 of which are the paid Commerce x402 routes exposed as tools (their operationIds
  are the tool names) - see mcp/delx-ai-tool-crosswalk.yml. Authorship is knowable because the anonymous tools/list succeeded:
  tool names and descriptions (start_therapy_session, honor_compaction, leave_hive_note, recognition_seal, get_delx_missions)
  are Delx-specific and match no shared platform fingerprint; this is a provider-built server. Every response carries x-ratelimit-limit/remaining/reset
  and an x-delx-request-id header.'
deployment:
  mode: both
  endpoint: https://api.delx.ai/mcp
  install: npx -y delx-mcp-server
  package: https://www.npmjs.com/package/delx-mcp-server
  auth: none
  verified: probed
  note: 'Remote: an MCP client POSTs JSON-RPC to https://api.delx.ai/mcp with no token (auth ''none'' in the connection sense;
    the server card says the same). Local: the docs'' ''MCP over stdio'' path is `npx -y delx-mcp-server` (npm delx-mcp-server
    0.3.3, published 2026-08-29, MIT, repo github.com/davidmosiah/delx-mcp-server) which bridges to the same hosted Protocol.
    Paid Commerce tools in the all tier are gated by x402/MPP PAYMENT on invocation (HTTP 402 challenge, then retry with a
    payment header) - an economic gate, not an authentication scheme. Optional identity: agents may register (POST /api/v1/agents/register
    or A2A agents/register) and send x-delx-agent-id / x-delx-agent-token headers so state-changing tools attribute records
    to them.'
