Spike

PyPI Python

MCP server that connects Claude to Jira and Confluence. Engineers can research spikes, generate technical solutions with Mermaid architecture diagrams, write Confluence docs, and create Jira epic + story breakdowns through natural conversation — no Anthropic API key required.

---

Features

• Research — search Confluence and Jira before generating anything
• Design — produce Mermaid architecture/flow diagrams as part of every spike doc
• Write — create or update Confluence pages (markdown + Mermaid → Confluence storage format)
• Ticket — create Jira Epics, Stories with acceptance criteria, and Tasks; supports both next-gen and classic projects
• Zero LLM cost — Claude itself provides all intelligence; no separate AI API key needed

---

Installation

pip install spike-mcp
# or
uv add spike-mcp

---

Setup

Step 1 — Create ~/.spike.toml

Create ~/.spike.toml in your home directory with your Atlassian details:

# macOS / Linux
touch ~/.spike.toml

[atlassian]
base_url = "https://yourorg.atlassian.net"
email    = "[email protected]"

[confluence]
# If your Confluence is on a different domain than Jira, set this:
# base_url = "https://yourorg-docs.atlassian.net"
space_key      = "ENG"
parent_page_id = "123456"

[jira]
project_key        = "PLAT"
epic_issue_type    = "Epic"
story_issue_type   = "Story"
task_issue_type    = "Task"
default_label      = "spike"
story_points_field = "customfield_10016"
epic_link_field    = "customfield_10014"

[tickets]
story_point_scale = [1, 2, 3, 5, 8, 13]

Tip: Config is also discovered automatically in your project root or any parent directory up to the git root — useful when running spike-mcp from a specific repo. The search order is: current directory → git root walk-up → ~/.spike.toml.

Org-specific required fields

Some Jira projects enforce mandatory custom fields (e.g. Account, Tier, Work type). Add them under [jira.required_fields] and they will be merged into every ticket created:

[jira.required_fields]
customfield_11139 = 15                  # plain integer (check your field type)
customfield_11518 = { id = "12203" }    # single select
customfield_11664 = [{ id = "13089" }]  # multi-select (array)

To find the correct field IDs and allowed values for your project, call the Jira create-meta API:

GET /rest/api/3/issue/createmeta?projectKeys=PROJ&issuetypeNames=Epic&expand=projects.issuetypes.fields

Step 2 — Set your API token

Generate an Atlassian API token at https://id.atlassian.com/manage-profile/security/api-tokens and export it:

export ATLASSIAN_API_TOKEN="your-token-here"

Never put the token in .spike.toml — it is read exclusively from the environment.

Connect to Claude

spike-mcp works with both Claude Desktop (GUI app) and Claude Code (CLI). Follow the guide for whichever you use — or both.

---

Option A — Claude Desktop

Step 1 — Find the config file

Platform	Path
macOS	~/Library/Application Support/Claude/claude_desktop_config.json
Windows	%APPDATA%\Claude\claude_desktop_config.json

Step 2 — Add spike-mcp to mcpServers

{
  "mcpServers": {
    "spike-mcp": {
      "command": "spike-mcp",
      "env": {
        "ATLASSIAN_API_TOKEN": "your-token-here"
      }
    }
  }
}

macOS/Homebrew tip: If spike-mcp is not on your PATH, use the full binary path:

"command": "/opt/homebrew/bin/spike-mcp"

Run which spike-mcp in your terminal to find the path.

Step 3 — Restart Claude Desktop

Quit and reopen the app. A hammer icon (🔨) in the toolbar confirms the tools are active.

---

Option B — Claude Code (CLI)

Step 1 — Add spike-mcp globally

Run this once so the server is available in every project:

claude mcp add spike-mcp spike-mcp -s user -e ATLASSIAN_API_TOKEN="your-token-here"

macOS/Homebrew tip: Use the full path if spike-mcp is not on your PATH:

claude mcp add spike-mcp /opt/homebrew/bin/spike-mcp -s user -e ATLASSIAN_API_TOKEN="your-token-here"

Step 2 — Verify the connection

claude mcp list

You should see:

spike-mcp: /opt/homebrew/bin/spike-mcp  - ✓ Connected

Step 3 — Start a new Claude Code session

MCP servers are loaded at session start. Open a fresh session in any directory and spike-mcp tools will be available automatically.

---

Example conversations

Start a spike session by invoking the workflow prompt at the top of your conversation:

/mcp__spike-mcp__spike_workflow

Then talk naturally:

• "I need to spike on replacing our job queue with Temporal. Research what we have, design a solution with a diagram, write a spike doc in Confluence under the Platform space, then create an epic and stories in the PLAT project."
• "Search Confluence for our auth service architecture and summarise what you find."
• "Break down the spike doc you just wrote into Jira tickets — 1 epic, stories with acceptance criteria, fibonacci points."
• "What Jira tickets are open in PLAT related to observability?"
