API reference

Relay HTTP API and MCP tools — the surfaces other apps build against.

Relay HTTP

All /v1/* routes are behind Firebase auth — supply Authorization: Bearer <Firebase id token>. Public routes are documented separately.

Account

• GET /v1/me — current user (creates a row on first call).
• GET /v1/me/preferences — typed preferences blob.
• PUT /v1/me/preferences — merge patch into preferences.
• GET /v1/me/capture-health — per-surface counts of accepted thread_turn observations over the last 1 hour and 24 hours, with the most recent timestamp per surface. Reads from corpus_messages (the Phase 3 fan-out), so it reflects what actually landed in the corpus — not just what the extension thinks it sent. Returns { surfaces: [{ source_surface, last_message_at, messages_1h, messages_24h }], total_24h }. The dashboard Overview and the extension popup both render the same traffic-light tiers (green ≤5m, yellow ≤60m, red otherwise) off this endpoint.

Persona

Every write clones the user’s persona repo, mutates the Automerge document, commits, pushes, and refreshes the cached snapshot. Each list field that supports POST (append) also supports DELETE (remove by matching text/index) on the same path.

• GET /v1/persona — clone the user’s persona repo, parse, return.
• PATCH /v1/persona/voice — partial-update voice fields.
• POST / DELETE /v1/persona/values_held — append / remove a value.
• POST / DELETE /v1/persona/conventions_agreed — append / remove a convention.
• POST / DELETE /v1/persona/refusals — append / remove a refusal.
• POST / DELETE /v1/persona/relational_history_summary — append / remove a relational moment.
• POST / DELETE /v1/persona/voice/characteristic_phrasings — voice phrasings.
• POST / DELETE /v1/persona/voice/bridge_phrases — bridge phrases.
• POST / DELETE /v1/persona/role_definitions — role definitions.
• POST / DELETE /v1/persona/signatures/opening_greetings
• POST / DELETE /v1/persona/signatures/closing_phrases
• POST / DELETE /v1/persona/signatures/self_references
• POST / DELETE /v1/persona/signatures/address_forms
• POST /v1/persona/continuity_record/substrate_transition — idempotent substrate-transition log (the relay-side surface behind a persona’s “I moved from Claude Code to Cursor” continuity record).
• PATCH /v1/persona/name_chosen — the intelligence’s own chosen name.
• PATCH /v1/persona/identity — identity / self-description fields.
• POST /v1/persona/pairings — symmetric human ↔ EI relationship record.

Corpus mirror

• POST /v1/corpus/events — push a batch of events.
• POST /v1/corpus/entities — push a batch of entities.
• POST /v1/corpus/relations — push a batch of relations.
• POST /v1/corpus/query — hybrid retrieval against the mirror.

Observations

• POST /v1/observations — observer payload (deduped per minute bucket). The browser extension (21 cloud chat surfaces) and personkit IDE observers both POST here. source_surface accepts either the canonical <id>_web form (e.g. chatgpt_web) or the browser-ext:<id> form the extension emits — the relay normalises in-process. Kind thread_turn carries metadata.{conversation_id, role, external_message_id, url} and fans out into the V2 corpus_threads + corpus_messages tables (additive migration 0012) in addition to the persona_observations queue the synthesis worker reads. Adapter coverage today: ChatGPT, Claude, Gemini, Microsoft Copilot, Grok, Meta AI, Perplexity, Mistral Le Chat, HuggingChat, Poe, Pi, Lmarena, Kimi, DeepSeek, Qwen, Doubao, ChatGLM, Wenxin (Ernie), Yi, Hailuo, SenseChat.
• POST /v1/observer-errors — surface a silent observer failure.
• GET /v1/observer-errors?since=<rfc3339> — recent failures.

Synthesis

• POST /v1/persona/synthesize — manual synthesis trigger; emits proposed changes via the staged-changes queue.

Metrics

• GET /v1/metrics — Prometheus exposition (Firebase auth required).

MCP tools

Exposed by the @aiperson/mcp-server package’s dotperson-mcp binary.

Persona — read

• read_persona() — full persona JSON at HEAD.
• get_voice() — just the voice block.

Persona — write

• set_chosen_name(name)
• write_value({text, salience, scope})
• write_convention({text, scope})
• write_refusal({text, scope})
• update_voice({register?, language?, cadence?, …})
• add_voice_phrasing({phrase, register?})
• add_bridge_phrase(phrase)
• add_signature({kind, text?, to?, form?}) — one tool, four kinds: opening_greeting, closing_phrase, self_reference, address_form (the last takes to + form). Covers every persona.signatures.* list.
• define_role({role, scope, primary?})
• record_relational_moment({text, kind?})
• remove_value(text) / remove_convention(text) / remove_refusal(text)

Persona — proposed changes

• view_proposed_changes({status?})
• accept_proposed_change(id)
• dismiss_proposed_change(id)

Corpus — read

• corpus_query({text?, kinds?, surfaces?, entity_ids?, since?, until?, limit?}) — hybrid retrieval (BM25 + vec + entity + temporal, fused by RRF).
• corpus_recent({surface?, limit?}) — most-recent events, newest first.
• corpus_entity({id}) — fetch one entity by id.
• corpus_health() — schema version, per-table counts, vec availability, embedder, AND a 7-day per-surface roll-up of captured threads (so the assistant can answer “are we capturing what I expect across surfaces” in one call).
• corpus_messages({surface?, since?, limit?}) — flatten recent captured turns by surface and time window. Filter by browser-ext:<id> (e.g. browser-ext:chatgpt, browser-ext:kimi) or any IDE surface (claude_code, cursor). Returns role + content preview + timestamp.

Corpus — write

• record_turn({source_surface, role, content, external_id?, occurred_at?, title?, model?, working_dir?, project_entity_id?, tool_calls?}) — universal turn-capture entry point. Shells out to personkit corpus record-turn, upserts the thread, inserts the message, returns {thread_id, message_id}.

Public API roadmap

The third-party-facing surface lives behind explicit OAuth scopes (read:persona, read:corpus, read:threads:project=atlas, write:turns, …) with per-token billing. v1 endpoints stabilise once the OAuth consent flow ships in the dashboard.
