Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 406, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability69
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1378 tokens (~114/item across 12 items; 12 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management20
- Stability check failed: schema churn in the 16 days we've observed: 0 tool removals, 4 breaking changes, 0 auth/transport breaks, 6 additions. See how to fix → Fail
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 Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 12 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 13 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 Priority — TypeScript Compiler Intelligence MCP server?
Priority — TypeScript Compiler Intelligence is a hosted endpoint at https://semanticreader.dev/mcp/registry, so there is nothing to install locally. 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 Priority — TypeScript Compiler Intelligence MCP server?
Priority — TypeScript Compiler Intelligence is an MCP server listed in the public MCP registry as dev.semanticreader/semantic-reader. Stateless TS/JS compiler facts for agents: references, imports, impact. No repo index or OAuth. This page covers its hosted endpoint (https://semanticreader.dev/mcp/registry).
Is the Priority — TypeScript Compiler Intelligence MCP server safe to use?
Priority — TypeScript Compiler Intelligence scores 66 out of 100 on VerifyMCP. 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 Priority — TypeScript Compiler Intelligence MCP server expose?
Priority — TypeScript Compiler Intelligence exposes 12 tools: open_snapshot, get_capabilities, find_symbol, get_definition, get_type, and 7 more. Their descriptions and schemas cost roughly 731 tokens of context every time the server is loaded.
Does the Priority — TypeScript Compiler Intelligence MCP server require authentication?
No. We connected to Priority — TypeScript Compiler Intelligence without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Priority — TypeScript Compiler Intelligence MCP server still maintained?
Priority — TypeScript Compiler Intelligence is still listed as active in the MCP registry. We last reached this channel on 29 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
