fix(spec+compiler): update MCP gateway OTLP headers to string-only (v1.13.0) by Copilot · Pull Request #25135 · github/gh-aw

Copilot · 2026-04-07T17:32:35Z

Summary

Updates the MCP Gateway Specification, JSON schemas, and compiler so that the headers field in the opentelemetry configuration is exclusively a string, removing the previously supported object form. The compiler passes the headers string through as-is via ${OTEL_EXPORTER_OTLP_HEADERS}. The MCP Gateway version has been bumped to v0.2.17, which includes the updated schema that accepts string headers.

Changes

Specification (`docs/src/content/docs/reference/mcp-gateway.md`)

Bumped version: 1.12.0 → 1.13.0
Section 4.1.3.6: Changed headers type from object | string to string; updated description to clarify the value is passed through as-is
Removed dual-form configuration examples; replaced with a single string-form example
Removed Section 4.1.3.6.1 (Headers String Format) — no parsing rules needed since the string is passed through unchanged
Updated requirements: added headers MUST be a string when provided; removed string-parsing requirement
Updated compliance test range: T-OTEL-001 through T-OTEL-012 → T-OTEL-001 through T-OTEL-010
Updated T-OTEL-006: changed from "object form headers sent" to "string headers passed through as-is"
Removed T-OTEL-011 and T-OTEL-012 (string-form parsing tests)
Updated Appendix A.6 and A.7: replaced object-form headers with string form
Added change log entry for v1.13.0

JSON Schemas

pkg/workflow/schemas/mcp-gateway-config.schema.json
docs/public/schemas/mcp-gateway-config.schema.json

Both: changed opentelemetryConfig.headers from oneOf [object, string] to plain string type with updated description.

Compiler (`pkg/workflow/mcp_renderer.go`)

Removed the Node.js bash preamble that converted OTEL_EXPORTER_OTLP_HEADERS from key=value,... format into a JSON object (_GH_AW_OTLP_HEADERS_JSON)
Gateway config now emits "headers": "${OTEL_EXPORTER_OTLP_HEADERS}" — the raw string value passed through as-is — instead of the previously injected JSON object

Tests (`pkg/workflow/mcp_renderer_test.go`)

Added TestRenderJSONMCPConfig_OTLPGateway covering three scenarios: endpoint+headers (verifies raw env var passthrough and no conversion preamble), endpoint only (no headers field), and no OTLP config (no opentelemetry section)

Gateway Version (`pkg/constants/version_constants.go`)

Bumped DefaultMCPGatewayVersion: v0.2.16 → v0.2.17
v0.2.16 had a bundled schema requiring headers to be an object, causing startup validation failures with the new string-form output; v0.2.17 accepts string headers

Workflow Lock Files

All 186 workflow lock files recompiled to reflect the updated compiler output and gateway version

Changeset

Type: minor
Description: Updated MCP gateway OpenTelemetry headers to string-only and removed object-form support in spec, schema, and compiler output. Headers are passed through as-is. Bumped gateway image to v0.2.17.

@copilot update compiler to emit string with headers value and NOT try to parse them to a JSON object.

Done in commit 58c4131. The compiler (mcp_renderer.go) no longer converts the headers string to a JSON object. The bash preamble with the Node.js JSON.stringify conversion has been removed, and the gateway config now emits "headers": "${OTEL_EXPORTER_OTLP_HEADERS}" — a plain JSON string that bash expands at runtime from the job-level env var. All 182 workflow lock files have been recompiled to reflect the change.

Pull request overview

Updates the MCP Gateway OTLP headers configuration across spec/schema/compiler so opentelemetry.headers is string-only and is passed through unchanged, and bumps the default MCP Gateway image version to one that accepts the new schema.

Changes:

Updated MCP Gateway config JSON schemas to make opentelemetry.headers a string (no object form).
Updated compiler rendering to emit OTLP headers as a string (removing the node-based conversion preamble).
Bumped default MCP Gateway version to v0.2.17 and recompiled workflow lock files to reference it.

 			configBuilder.WriteString(",\n              \"opentelemetry\": {\n")
 			fmt.Fprintf(&configBuilder, "                \"endpoint\": %q,\n", options.GatewayConfig.OTLPEndpoint)
 			if options.GatewayConfig.OTLPHeaders != "" {

+				configBuilder.WriteString("                \"headers\": \"${OTEL_EXPORTER_OTLP_HEADERS}\",\n")


The generated JSON uses an unescaped shell expansion inside a JSON string ("headers": "${OTEL_EXPORTER_OTLP_HEADERS}"). If OTEL_EXPORTER_OTLP_HEADERS contains characters like quotes, backslashes, or newlines, the resulting gateway config will become invalid JSON. Consider JSON-escaping the env var value before inserting it into the config (without parsing it), or otherwise constraining/validating the allowed characters so the emitted config is always valid JSON.

 		// Per MCP Gateway Specification §4.1.3.6 and the opentelemetryConfig schema.
 		if options.GatewayConfig.OTLPEndpoint != "" {
 			configBuilder.WriteString(",\n              \"opentelemetry\": {\n")
 			fmt.Fprintf(&configBuilder, "                \"endpoint\": %q,\n", options.GatewayConfig.OTLPEndpoint)

+				configBuilder.WriteString("                \"headers\": \"${OTEL_EXPORTER_OTLP_HEADERS}\",\n")


This change alters OTLP header rendering (removes the preamble + switches to string passthrough), but there isn’t a unit test asserting the new emitted gateway opentelemetry JSON (e.g., that headers is a JSON string and that no node/bash preamble is emitted). Adding a focused test for RenderJSONMCPConfig with GatewayConfig.OTLPEndpoint+OTLPHeaders would guard against regressions in config shape and heredoc output.

@copilot review comments

Both review comments addressed in commit 0a519ca:

JSON safety (mcp_renderer.go:199-203): Added a bash preamble before the heredoc that JSON-escapes OTEL_EXPORTER_OTLP_HEADERS into _GH_AW_OTLP_HEADERS_ESC (escapes backslashes then double quotes using bash parameter substitution). The heredoc now references ${_GH_AW_OTLP_HEADERS_ESC} instead of the raw env var.
Missing test (mcp_renderer.go:191-203): Added TestRenderJSONMCPConfig_OTLPGateway with three cases: endpoint+headers, endpoint only, and no OTLP config. Asserts the preamble and ${_GH_AW_OTLP_HEADERS_ESC} reference appear when headers are configured, the old _GH_AW_OTLP_HEADERS_JSON variable is never present, and the endpoint value is emitted correctly.

@copilot remove JSON escaping, pass header as is

Done in commit 5eb4433. Removed the JSON-escaping preamble; the gateway config now emits "headers": "${OTEL_EXPORTER_OTLP_HEADERS}" directly. Updated the unit test to assert no escaping preamble is present and that the raw env var reference is used.
