## MCP tools (4)

### `tteop_build_envelope` (~281 tokens)

Build a TTEOP v0.1-draft schema-conforming telemetry envelope from token counts. Computes Yield (Υ), Leverage (L), Velocity (V), output_fraction (F), and log_leverage (D). No data is submitted or persisted. Returns the complete envelope as JSON.

Input parameters:

- `cache_read`: Cache-read tokens, or null when unavailable.
- `cache_write`: Cache-write tokens, or null when unavailable.
- `cohort_id` (string): Cohort identifier for private-managed-cohort mode. Requires operator_key.
- `input` (integer, required): Fresh input tokens (non-negative integer, required).
- `model` (string): Model identifier (e.g., 'claude-sonnet-4', 'gpt-4o').
- `operator_key` (string): Pseudonymous operator identifier. Must not contain real-world identity.
- `output` (integer, required): Output tokens (non-negative integer, required).
- `privacy_mode` (string): Privacy mode. Default: public-pseudonymous.
- `provenance_level` (string): Provenance level. Default: self-reported.
- `provider` (string): Provider name (e.g., 'anthropic', 'openai', 'google').
- `tool` (string): AI tool name (e.g., 'claude-code', 'cursor', 'copilot').

### `tteop_validate_envelope` (~91 tokens)

Validate a TTEOP v0.1-draft telemetry envelope against the JSON Schema and semantic rules. Returns validation status, schema errors, semantic errors, warnings, and computed metrics if valid.

Input parameters:

- `envelope` (object, required): The TTEOP telemetry envelope to validate (as a JSON object).
- `expected_profile` (string): If set, asserts the envelope's privacy mode matches this profile.

### `tteop_describe_protocol` (~48 tokens)

Get TTEOP protocol metadata: version, supported versions, privacy modes, provenance levels, forbidden fields, metric definitions (formulas, symbols, rounding), and schema/spec URLs.

### `tteop_run_conformance` (~62 tokens)

Run the TTEOP conformance suite: canonical vector invariants, zero-input/zero-output null semantics, missing-cache handling, build-validate round-trip, forbidden field detection, and banker's rounding. Returns pass/fail counts and detailed results.

## Common questions

### What is the io.github.SunrisesIllNeverSee/tteop-mcp server?

io.github.SunrisesIllNeverSee/tteop-mcp is listed in the public MCP registry as io.github.SunrisesIllNeverSee/tteop-mcp. Build, validate, and describe TTEOP telemetry envelopes for AI operator token efficiency. This page covers its npm package (tteop-mcp).

### Is the io.github.SunrisesIllNeverSee/tteop-mcp server safe to use?

io.github.SunrisesIllNeverSee/tteop-mcp scores 93 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 21 September 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. 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.SunrisesIllNeverSee/tteop-mcp server expose?

io.github.SunrisesIllNeverSee/tteop-mcp exposes 4 tools: tteop_build_envelope, tteop_validate_envelope, tteop_describe_protocol, tteop_run_conformance. Their descriptions and schemas cost roughly 482 tokens of context every time the server is loaded.

### Is the io.github.SunrisesIllNeverSee/tteop-mcp server still maintained?

io.github.SunrisesIllNeverSee/tteop-mcp is still listed as active in the MCP registry. We last reached this channel on 21 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 io.github.SunrisesIllNeverSee/tteop-mcp server under?

io.github.SunrisesIllNeverSee/tteop-mcp declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
