Expand MCP acronym to "Model Context Protocol" on first use in documentation

[Copilot]

The term "MCP" appeared throughout documentation without expansion, creating confusion for new users unfamiliar with the Model Context Protocol.

Changes

Updated 27 files to expand "MCP" to "Model Context Protocol (MCP)" on first occurrence per page:

• Reference docs (11 files): tools, frontmatter, engines, sandbox, safe-outputs, compilation-process, imports, tokens, permissions, environment-variables, frontmatter-full
• Guides (7 files): getting-started-mcp, web-search, custom-safe-outputs, packaging-imports, researchplanassign, security
• Setup (2 files): mcp-server, cli
• Introduction (2 files): architecture, how-it-works
• Examples (3 files): projectops, research-planning, README
• Troubleshooting (2 files): common-issues, errors

Subsequent uses within the same page continue using "MCP" alone for readability. Glossary entry preserved as authoritative reference.

Example

Before:

**Note:** Some engines require third-party MCP servers for web search.

After:

**Note:** Some engines require third-party Model Context Protocol (MCP) servers for web search.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• telemetry.astro.build
  • Triggering command: /opt/hostedtoolcache/node/24.12.0/x64/bin/node node /home/REDACTED/work/gh-aw/gh-aw/docs/node_modules/.bin/astro build (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

This section details on the original issue you should resolve

<issue_title>[plan] Expand MCP acronym to "Model Context Protocol" on first use</issue_title>
<issue_description>## Objective

Expand the "MCP" acronym to "Model Context Protocol (MCP)" on first use throughout the documentation.

Context

The term "MCP" is used frequently without expanding the acronym, which confuses beginners who don't know what it stands for.

Implementation

On first use of "MCP" on each page, write:

Model Context Protocol (MCP)

Subsequent uses on the same page can use "MCP" alone.

Files to Update

Search for first occurrence of "MCP" in:

• docs/src/content/docs/guides/quick-start.md
• docs/src/content/docs/guides/agentic-authoring.mdx
• docs/src/content/docs/reference/frontmatter.md
• All example workflow documentation
• Other guides that mention MCP

Approach

Use grep to find all files mentioning MCP:

grep -r "MCP" docs/src/content/docs/ --files-with-matches

Then update the first occurrence in each file.

Acceptance Criteria

• First use of MCP on each page expands to "Model Context Protocol (MCP)"
• Subsequent uses can use "MCP" alone
• Glossary entry for MCP remains as the full reference
• Change is consistent across all documentation
