Azure/gpt-rag-mcp is a Python server that exposes GPT-RAG capabilities through the Model Context Protocol. It is deployed with Azure resources and consumed by GPT-RAG through its MCP strategy, while the catalogue provides instructions, skills, and agents for operating it.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00038 | $0.00342 |
| Opus 5 | $0.00019 | $0.00171 |
| Sonnet 5 | $0.00008 | $0.00068 |
| Haiku 4.5 | $0.00004 | $0.00034 |
Grade A, and why
mcp-capability-development scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
MCP capability development
- Classify the capability as a tool, resource, prompt, or transport concern
and confirm
Azure/gpt-rag-mcpowns it. - Identify the orchestrator outcome, trust boundary, authorization model, external effects, limits, and compatibility constraints.
- Define a narrow typed contract: name, description, arguments, defaults, validation, result shape, error behavior, and bounds.
- Put focused logic in
src/tools/,src/resources/, orsrc/prompts/and keep registration insrc/server.pythin. - Treat all inputs and upstream content as untrusted. Validate schemes, hosts, identifiers, paths, sizes, and counts before effects.
- Add timeouts, output limits, least-privilege access, and actionable non-sensitive errors at external boundaries.
- Preserve compatibility or document and coordinate migration with the
orchestrator and
Azure/GPT-RAG. - Add focused behavior or contract tests when feasible.
- Restore with
uv sync, check import or startup behavior, exercise the capability with the MCP Inspector, and run orchestrator end to end when the integration contract changes. - Update this repository's documentation and the GPT-RAG docs branch when users or operators observe the change.
Never place this runtime capability under .github/; that directory contains
engineering-time Copilot assets only.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

mcp-capability-development is a skill published in the GitHub repository Azure/gpt-rag-mcp (22 stars, last pushed 7d ago), licensed MIT. It adds 38 tokens to every session and 342 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
