Safety-aware MCP server for Linear issues, projects, cycles, and dependencies.
Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs hatchling.build at install time, a recognised native-build step with no shell scripting around it. View diagnostics → Pass
- 0 of 29 dependencies flagged as unhealthy. View diagnostics → Pass
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 70 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability64
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 2005 tokens (~47/item across 42 items; 42 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management87
- Stability observed for 26 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety80
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 1 of 5 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "remove_issue_from_project" implies "remove" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Partial
- An AI judge read all 42 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the Abscissa MCP server?
Abscissa runs locally as a PyPI package, launched with uvx abscissa. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

What is the Abscissa MCP server?
Abscissa is an MCP server listed in the public MCP registry as io.github.KazKozDev/abscissa. Safety-aware MCP server for Linear issues, projects, cycles, and dependencies. This page covers its PyPI package (abscissa).
Is the Abscissa MCP server safe to use?
Abscissa scores 77 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Abscissa MCP server expose?
Abscissa exposes 42 tools: get_current_user, create_issue, update_issue, set_issue_project, remove_issue_from_project, and 37 more. Their descriptions and schemas cost roughly 2,005 tokens of context every time the server is loaded.
Is the Abscissa MCP server still maintained?
Abscissa is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the Abscissa MCP server under?
Abscissa declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
