What is jira8_mcp AGENTS.md?

A set of instructions for AI agents working on a TypeScript MCP server that provides read access to an internal Jira 8 system.

It is for guiding work on Jira access, session validation, server construction, HTTP requests, and the separation between authentication and tools.

It explains the project's purpose, architecture boundaries, authentication flow, coding standards, and how to navigate the codebase.

Token cost

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	$0.02637	$0.02637
Opus 5.5	$0.01055	$0.01055

Security

Grade A, and why

jira8_mcp AGENTS.md 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 2mo 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 Is This Project?

jira-run-mcp is a TypeScript MCP (Model Context Protocol) server that provides AI agents with read access to an internal Jira 8 instance. Authentication uses Playwright-based SSO session bootstrap; API calls use HTTP with stored cookies.

Architecture Rules

Server uses factory pattern. Each incoming MCP request gets a new McpServer + StreamableHTTPServerTransport pair. Never reuse a server instance across requests.
Auth is isolated from tools. Tools call loadAndValidateSession() — they never touch Playwright or browser state. Session validation must not launch a browser.
HTTP-first for Jira access. All Jira REST API calls go through src/jira/http-client.ts using Axios. Playwright is used only for the interactive SSO login CLI (jira-auth-login). loadAndValidateSession() never launches a browser: it tries the stored cookie session, then optional HTTP Basic Auth, then returns AUTH_REQUIRED / SESSION_EXPIRED.
Zod validates everything. Environment variables (src/config.ts), tool inputs (each tool's schema), and Jira responses are all validated.

Coding Standards

TypeScript strict mode. No any. No implicit types.
ESM with .js extensions. All imports must end in .js (NodeNext module resolution).
Errors use McpError. Every business error must use the McpError class with a typed code. Use factory helpers from src/errors.ts.
Tool errors set isError: true. MCP clients rely on this flag. Never return an error as normal content.
3xx from Jira = session expired. Always treat redirects as auth failure. validateStatus accepts only 2xx.
Validate before saving sessions. The playwright-auth.ts module validates a candidate session against Jira before writing it to disk.
Utility functions in src/utils.ts. Shared helpers (e.g. date formatting, string manipulation) must live in src/utils.ts, not inline in tool or handler files.
Prefer libraries over hand-rolled code. For common tasks (date formatting, duration parsing, HTTP retry, etc.), use well-known npm packages instead of writing custom implementations. Only write a manual helper if the logic is trivially small (< 5 lines) and adding a dependency would be disproportionate.
Raw API response types in src/types/jira-api.ts. Types that mirror the exact shape of Jira/Tempo REST API responses must live in src/types/jira-api.ts, separate from the normalized application interfaces in src/types.ts. This keeps API contracts independently trackable and supports future API documentation generation.

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.
