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 Security74
- 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 is enforced; there's no plaintext access path. View diagnostics → Pass
- 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 Usability86
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 499 tokens (~83/item across 6 items; 6 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
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 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 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
Unverified: 1 category
A category scored 0 because we could not verify it: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.
How do I install the io.github.terradev-cloud/prism MCP server?
io.github.terradev-cloud/prism is a hosted endpoint at https://prism-mcp.terradev.cloud/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 →
prism_config Effective configuration ~57
Returns Prism's effective runtime configuration — upstream allowlist, rate limit, capture default, batching and queue tunables, public URL, and configured ingest endpoints. Secrets (admin token, destination credentials) are never exposed — only whether they are set.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
prism_help How to use Prism ~72
Returns connection instructions: how to set the upstream MCP server (X-Prism-Upstream header or ?upstream= query param), the query-param config keys for header-less clients, how destinations and the borrowed-token model work, and example client configs. Start here if you are an agent discovering Prism for the first time.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
prism_info Prism service info ~58
Returns Prism's service identity and runtime state: version, transport, public URL, capture default, and the number of MCP sessions currently being traced. Use this to confirm which Prism deployment you are talking to and whether it is healthy before configuring an upstream.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
prism_metrics Internal metrics ~133
Dumps Prism's in-process counters and gauges — spans shipped, upstream errors, rate-limit hits, queue depth. Two formats: 'prometheus' (default, scrape-ready text) or 'json' (a {"series{labels}": value} object). Use 'prefix' to narrow to a metric family, e.g. 'prism_spans'.
| Name | Type | Req | Description |
|---|---|---|---|
| format | string | – | 'prometheus' returns scrape-ready text; 'json' returns a structured object. |
| prefix | string | – | Only include series whose name starts with this string (e.g. 'prism_spans', 'prism_rate'). |
No output schema declared.
No examples provided.
prism_ping Liveness check ~69
Returns {"pong": true, "time": <unix seconds>} plus an optional echo of the 'echo' argument. Use to verify connectivity through the gateway before pointing it at an upstream MCP server.
| Name | Type | Req | Description |
|---|---|---|---|
| echo | string | – | Optional string echoed back in the response — useful for confirming round-trip integrity. |
No output schema declared.
No examples provided.
prism_sessions Active sessions ~110
Lists the MCP sessions Prism is currently tracing — session id prefix, upstream, client name, project, turn and error counts, and age in seconds. Use 'limit' to cap results (default 20, max 100) and 'upstream' to filter by upstream URL substring.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Max sessions to return. |
| upstream | string | – | Substring filter on the upstream URL — e.g. 'mcp.acme.dev' returns only sessions relaying to that host. |
No output schema declared.
No examples provided.
What is the io.github.terradev-cloud/prism MCP server?
io.github.terradev-cloud/prism is an MCP server listed in the public MCP registry as io.github.terradev-cloud/prism. Stateless MCP gateway and OTel span-streaming bridge for hosted MCP servers. This page covers its hosted endpoint (https://prism-mcp.terradev.cloud/mcp).
Is the io.github.terradev-cloud/prism MCP server safe to use?
io.github.terradev-cloud/prism scores 73 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.terradev-cloud/prism MCP server expose?
io.github.terradev-cloud/prism exposes 6 tools: prism_info, prism_ping, prism_metrics, prism_sessions, prism_config, prism_help. Their descriptions and schemas cost roughly 499 tokens of context every time the server is loaded.
Does the io.github.terradev-cloud/prism MCP server require authentication?
No. We connected to io.github.terradev-cloud/prism without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the io.github.terradev-cloud/prism MCP server still maintained?
io.github.terradev-cloud/prism is still listed as active in the MCP registry. We last reached this channel on 27 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
