  https://github.com/awslabs/mcp (AWS Labs, first-party) and
  https://docs.aws.amazon.com/aws-mcp/latest/userguide/what-is-mcp-server.html — both tool lists read
  live by anonymous JSON-RPC tools/list on 2026-09-17 and saved verbatim alongside this file.
provider: Amazon Lex
providerId: amazon-lex
note: >-
  AWS ships NO Amazon Lex-specific MCP server. There is no create_bot tool, no recognize_text tool, and
  no Lex tool namespace anywhere in the awslabs/mcp catalog. Amazon Lex is reachable through AWS's two
  general-purpose first-party servers, which expose AWS APIs GENERICALLY — a sandboxed script/boto3
  executor and a documentation reader — so an agent calls Lex the way it would call any AWS service,
  by naming the boto3 client "lexv2-models" or "lexv2-runtime" inside aws___run_script. That
  distinction is the finding: the servers are real, first-party and answered tools/list anonymously,
  but Amazon Lex itself has no per-operation tool surface. Recorded as published on the strength of the
  servers, not on the strength of Lex's own agent affordances.
deployment:
  mode: both
  endpoint: https://aws-mcp.us-east-1.api.aws/mcp
  install: uvx mcp-proxy-for-aws@latest https://aws-mcp.us-east-1.api.aws/mcp
  package: https://pypi.org/project/awslabs.aws-api-mcp-server/
  auth: api-key
  verified: probed
  note: >-
    `auth: api-key` means AWS SigV4 / IAM credentials. tools/list answered anonymously (HTTP 200, real
    inputSchemas, saved verbatim) but every tool CALL executes against the caller's own AWS credentials
    under IAM permissions with CloudTrail logging. The remote endpoint is normally reached through the
    local `mcp-proxy-for-aws` proxy, which performs the SigV4 signing; a bare MCP client POSTing to the
    URL can list tools but cannot execute an AWS operation.

    Amazon Lex's 107 Model Building V2 operations and 6 Runtime V2 operations are invoked as boto3
    lexv2-models / lexv2-runtime calls, not as named MCP tools.
