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
- Authorisation not fully verified: no authorisation is required to call this server, and 7 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- 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 Usability82
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 798 tokens (~114/item across 7 items; 7 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
How do I install the io.github.AdrianStauffer/copilot-studio-friction-index MCP server?
io.github.AdrianStauffer/copilot-studio-friction-index is a hosted endpoint at https://pcghrrzwqshejvifoxjq.supabase.co/functions/v1/friction-mcp, 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 →
get_current_drift Get current drift (status page) ~64
What is currently broken or regressed in Microsoft Copilot Studio, per the continuously verified Friction Index: all records with status open or regressed (newest status change first) plus register health counts (total records, share verified within 90 days, status distribution).
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_friction_record Get a full friction record ~110
The complete friction record for a slug: status, dates, confidence, severity, time cost, categories, channels, license context, error codes/messages, dated evidence list, and the six body sections as markdown (symptom checklist, cause, fix with solution classes, verification steps, fallback, prevention). Cite the returned URL; a German version exists at the german_version URL.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | Record slug, e.g. "flowactiontimedout" (from search/list results). |
No output schema declared.
No examples provided.
get_pattern Get a full pattern ~63
The complete prevention pattern for a slug: the pattern, when to use it, and step-by-step instructions as markdown, plus the friction records it protects against.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | Pattern slug, e.g. "async-continuation" (from list_patterns). |
No output schema declared.
No examples provided.
list_frictions List friction records ~97
Browse the register: compact list of all published friction records, sorted by last-verified date (newest first). Filter by status and/or category.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Optional category filter. |
| status | string | – | Optional status filter: "open" (problem exists), "mitigated" (reliable workaround), "fixed" (resolved and re-verified), "regressed" (was fixed, is back). |
No output schema declared.
No examples provided.
list_patterns List prevention patterns ~47
All reusable build patterns that prevent whole classes of Copilot Studio friction before they happen (e.g. async continuation for the 100-second flow limit), each with its problem class and related records.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
lookup_error Look up a verbatim error ~79
Exact/substring match against all known Copilot Studio error codes and error messages in the register. The fastest path when you have a verbatim error string (e.g. "FlowActionTimedOut"). Returns the matching record(s) with the citable URL.
| Name | Type | Req | Description |
|---|---|---|---|
| error | string | yes | The error code or error message, as verbatim as possible. |
No output schema declared.
No examples provided.
search_frictions Search friction records ~198
Ranked search over the Copilot Studio Friction Index. Exact error-code/message hits rank first, then title, alias, summary and symptom-checklist matches (solution bodies are NOT searched — an empty result means no record is indexed under these terms, not that the register lacks a fix). Use this when the user describes a Copilot Studio problem, symptom or keyword. Returns compact records with slug, status, severity, last-verified date and the citable powerleap.ch URL.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Optional category filter. |
| limit | integer | – | Maximum results. |
| query | string | yes | Error string, symptom or keywords, e.g. "flow times out after 100 seconds". |
| status | string | – | Optional status filter: "open" (problem exists), "mitigated" (reliable workaround), "fixed" (resolved and re-verified), "regressed" (was fixed, is back). |
No output schema declared.
No examples provided.

This page covers its hosted endpoint (https://pcghrrzwqshejvifoxjq.supabase.co/functions/v1/friction-mcp).
Is the io.github.AdrianStauffer/copilot-studio-friction-index MCP server safe to use?
io.github.AdrianStauffer/copilot-studio-friction-index scores 80 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 io.github.AdrianStauffer/copilot-studio-friction-index MCP server expose?
io.github.AdrianStauffer/copilot-studio-friction-index exposes 7 tools: search_frictions, lookup_error, get_friction_record, list_frictions, get_current_drift, and 2 more. Their descriptions and schemas cost roughly 658 tokens of context every time the server is loaded.
Does the io.github.AdrianStauffer/copilot-studio-friction-index MCP server require authentication?
No. We connected to io.github.AdrianStauffer/copilot-studio-friction-index without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the io.github.AdrianStauffer/copilot-studio-friction-index MCP server still maintained?
io.github.AdrianStauffer/copilot-studio-friction-index 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.
